Should You Worry About West Nile Virus This Summer?

Written by Chem-Wise on . Posted in Blog

Summer is on its way, which means campfires, marshmallows, and growing concerns about the West Nile virus.

According to the Centers for Disease Control and Prevention, a total of 47 states reported West Nile virus infections.

Approximately 2,122 individuals contracted the disease, and some of these cases resulted in neuroinvasive conditions such as encephalitis, meningitis, or both.

In Illinois, 34 West Nile mosquito samples reported positive, 15 humans contracted the condition, and 2 residents died from the virus in 2014 alone.

What Is West Nile Virus?

West Nile virus is anthropod-borne virus (arbovirus). Although scientists first identified the virus in Uganda in 1937, the virus has since spread to many other areas of the world. In 1999, the US had its first major outbreak, and more than 1,700 people have died because of the condition since then.

Common Symptoms

Most people infected with the virus don’t notice or experience any signs or symptoms. Some individuals may experience a mild headache or fever, but often the symptoms go away on their own. According to Dr. Jorge Parada, infectious disease specialist at the Stritch School of Medicine, about 75% of West Nile victims don’t feel sick enough to seek medical attention.

However, some moderate cases of the disease can result in:

  • Severe headache
  • High fever
  • Disorientation
  • Sudden weakness
  • Body aches and joint pains
  • Vomiting and diarrhea
  • Rash

And in more severe cases, individuals may experience encephalitis or meningitis (inflammation of the brain or surrounding tissues). These conditions can trigger:

  • Seizures
  • Tremors
  • Paralysis
  • Coma

Recovery from more severe cases can take several weeks or months, and a few individuals have permanent neurologic effects.

How Does It Spread?

West Nile Virus most commonly spreads via infected mosquitos, which become infected when they feed on infected birds.

But in a small number of cases, the virus spreads through blood transfusions and organ transplants. Rarely, an infected mother can transfer the disease to the baby during pregnancy, delivery, or breastfeeding.

What Can You Do to Prevent It?

Although West Nile virus symptoms and statistics sound frightening, keep in mind that the average mosquito does not have the virus. Additionally, some experts estimate that less than 1% of those infected with West Nile develop severe illnesses such as encephalitis or meningitis.

People with certain medical conditions (diabetes, kidney disease, cancer, etc.) have a greater risk for experiencing more severe symptoms. But you can take steps to reduce your likelihood of catching the disease, including the following 1. Don’t Forget Insect Repellent

Since the condition spreads via mosquitos, applying insect repellant whenever you spend time outside can help keep you safe. Look for repellents with ingredients such as DEET, Picaridin, and oil of lemon eucalyptus.

These chemicals can cause harmful side effects if you inhale or swallow the spray, so only apply the repellent as directed on the label. Wash the spray off your skin as soon as you go indoors again.

  1. Use Clothing to Cover Up

Short sleeves, t-shirts, and tank tops may provide some relieve from hot Chicago summers. But most experts recommend using clothing to cover up and reduce skin exposure to mosquitos. Some mosquitoes may bite through thin clothing, so wear heavy jeans and long sleeved jackets during peak mosquito biting hours (dusk to dawn).

  1. Install or Repair Screens

Your home should be a safe haven from insects, so do everything you can to keep mosquitoes outside. Repair or install screens on windows and doors. If you have air conditioning or fans, use them regularly. Mosquitoes become less active during cooler temperatures.

     4.  Cover Outdoor Playpens with Netting

Many doctors agree that you shouldn’t apply insect repellent on children younger than 2 years old. To protect them from mosquitoes when they play outdoors, cover any playpens or baby carriers with a fine mesh netting. If you wish, purchase playpens and cribs with mosquito netting already attached.

  1. Remove Any Standing Water

Mosquitoes need standing water to breed, and they can reproduce in any puddle or pool that lasts for more than four days. Removing standing water significantly reduces the number of mosquitoes buzzing around your home.

Pay close attention to the following, as these can easily collect water:

  • Discarded metal cans, plastic containers, and ceramic pots
  • Old replacement tires and trash cans
  • Clogged roof gutters and downspouts
  • Plastic wading pools and wheelbarrows
  • Birdbaths and ornamental ponds

If you have a swimming pool, regularly clean it and check that it’s properly chlorinated. Water can also collect on top of pool covers, so siphon away the water with a garden hose as needed.

Call Pest Control

Because of the health risks mosquitoes pose, call an expert to help you eliminate any infestations you see on your yard or property. Pest control can also spot any potentially problematic areas that could harbor the insects in the future. Don’t hesitate to call in an expert if you worry about West Nile virus. Contact us today!

9 Reasons Why Rats Are Even Grosser Than You Thought

Written by Chem-Wise on . Posted in Blog

Even if you don’t mind guinea pigs, gerbils, and chubby little hamsters, rats are probably not your favorite rodent. With their big black eyes, pointed snouts, and thick tails, you might already feel disgusted by rats and their mouse brethren. And if rats don’t creep you out already, they’re about to.

Rats are ingenious and resilient little creatures, but that doesn’t always bode well for you if they get in your house. Read on for 9 reasons why rats are even grosser than you thought and why you should get rid of a rat infestation in your home as quickly as you can.

  • Rats Are Found All over the World

Rats have a reputation for sneaking onto ships. And before the invention of airplanes, ships were the primary way for people to travel around the world. For centuries, the rats took full advantage of this transportation system. When humans on ships arrived at their destinations, the rats arrived along with them. As a result, rats live almost everywhere in the world.

Even to this day, you can find rats can on ships at sea, traveling between continents.

  • Rats Can Fit Through Small Spaces

Seal your house as well as you like, and the rats still might get in. Even if you think you’ve covered every nook and cranny, if a rat thinks it might find something it likes in your house, it can chew through almost any material and squeeze through spaces the size of a quarter.

Rats use their sharp teeth to munch through brick, wood, and even lead.

  • Rats Can Produce Thousands of Offspring

If left to their own devices, rats will mate like rabbits. A single female rat can mate with hundreds of males throughout the yearthey have even more fertility cycles than humans. With this kind of virility, rats can produce thousands of offspring in their short lifetimes. While they only live two to three years, they can have as many as 2,000 babies annually.

Although they have the potential to have thousands of offspring, most rats produce under 100.

  • Rats Can Swim

Have you ever seen a scary movie where a monster or creature came up through the sewer pipes and out the toilet? Well, you actually can find a rat in your toilet in a similar fashion. Rats have the ability to swim up to half a mile, and they can tread water for days. If you ever flush a rat down the toilet, don’t feel surprised if it comes back up the same way.

Because of their strong swimming abilities, rats have even been known to swim between different islands.

  • Rats Used to Populate an Entire Island

In 1780, a Japanese ship wrecked on an island in Alaska. As with most ships, especially at the time, this Japanese ship carried a few rats. When the ship crashed, the rats took refuge on the island and quickly established a thriving population. The rats did so well on the island that the land itself earned the name of “Rat Island.”

Unfortunately for the island’s native bird species, the rats wreaked havoc on their populations. To prevent further damage, the US government staged a rat intervention in 2008. Rat Island was declared rat-free in 2009 and was renamed Hawadax Island in 2012.

  • Rats Used to Fight Dogs

In a practice called rat-baiting, rats fought against a dog in a large pit to see how long it would take the dog to kill them. The practice was first developed in London after other forms of animal fighting became illegal-but not rat fighting. To keep their betting games going, Londoners put rats in a pit with a dog, started a clock, and watched the animals go at it.

Rat-baiting is now illegal, although dogs can still effectively kill rats as a pest control measure.

  • Rats Transmit Disease

Although this should seem obvious, one of the biggest reasons rats are creepy is that they carry disease. Rats have transmitted everything from hemorrhagic fevers and the black plague to humans around the world.

  • Rats Can Survive Great Falls

If you ever encounter a rat on a balcony, don’t think throwing it off will kill it. Rats can survive falls of up to 50 feet and escape unscathed.

  • Rats Can Laugh

When you picture a rat, the last thing you want to see is it laughing. Rather than seem joyous, a laughing rat seems like something from a nightmare. However, scientists have reported that lab rats make happy squeaking noises when they play with other rats, and when the scientists tickle them. Before you’re taken in with this seemingly happy picture, remember all the other creepy facts you’ve learned about rats.


Rats are unpleasant yet innovative creatures. If you find any signs of rats in your home, such as droppings, scratching noises, or gnawing damage, call a pest control company right away. For resilient rats, you need resilient professionals.

Bees, Wasps, and Hornets-Oh My! How to Spot the Difference

Written by Chem-Wise on . Posted in Blog

During the spring and summer, you love to bask in the sunshine as much as possible. You sit in your favorite chair and sip lemonade, or perhaps you run on the grass and play games with your children.

But while you’re enjoying that light breeze on your face, you happen to feel a tickle on your arm.


Something stung you. The red bump starts to swell, and then the insect flies past your nose.

Not sure what it was? Use the following guide to help you determine the culprit.


Chicago is home to a variety of bees due to the city’s hobbyists and green entrepreneurs. Many restaurants rely on the natural honey to create cocktails or honey wine.

Yet while beekeepers tend to their hives in their backyards and balconies, you can’t help but wonder if the insect that stung you was an escapee or a natural local.

Bumble Bee

Bumblebees are fat and furry in appearance, with black and yellow (and occasionally orange) markings. They are social bees that most often live in the wild. They live in nests with 50 to 400 bees, and these nests tend to stay mostly in the ground or slightly higher. They only make small amounts of a honey-like substance that they eat themselves.

Though bumblebees have a loud buzz, they are not aggressive in nature. However, their smooth stinger enables them to sting more than once if aggravated.

Carpenter Bee

Carpenter bees look like bumblebees in size and appearance. They are fuzzy and large with black and yellow markings. However, unlike bumblebees, they are solitary creatures. They build nests in trees and in the frames of buildings where they can drill into the wood.

The male carpenter bee does not have a stinger, but it may approach people who move quickly or wave a hand in the air. If you’re approached, don’t panic; the bees are harmless. The female carpenter bee can sting, but seldom does. You must handle and provoke her a great deal before she will sting.

Honey Bee

Honeybees are smaller and slimmer than bumblebees, but they’re not as angular as wasps. They live in hives of up to 50,000 or 60,000 bees, which are often tended by beekeepers. As their name implies, honeybees make a lot of honey, which beekeepers can harvest to sell or eat.

Unfortunately, many honeybees are dying due to Colony Collapse disorder. And because they have barbed stingers, they can only sting once. The stinger lodges into its attacker, causing the stinger to rip from its body. Because of this, honeybees only sting as a last resort to protect their colony.


While bees tend to be harmless, wasps are often more aggressive. You can often tell the difference between wasps and bees by their hair and body shape. Wasps tend to be slimmer than bees, with elongated bodies. They also lack the body hair that makes bees look fuzzy. Yellow Jackets

True to their name, yellow jackets are black with prominent yellow stripes. They have narrow wings that fold longitudinally when resting. You can recognize a yellow jacket by the way it flies: a rapid, side-to-side pattern right before it lands.

Unlike bees, yellow jackets do not produce honey. Rather, they scavenge and eat meats and sweets, which is why you can often find them in parks or picnic areas.

Yellow jackets create enclosed nests below ground, which they defend aggressively. Because they can repeatedly sting if provoked, you should take care to check for yellow jacket nests before mowing your lawn.

Cicada Killer Wasps

Chicago is home to unique wasps known as cicada killer wasps. Unlike other wasp species, many nature-lovers appreciate these insects for the work that they do. Rather than attacking humans, cicada killer wasps kill cicadas that invade and damage neighborhood trees.

Before you grab the bug spray, double check the wasp’s appearance. Cicada killer wasps are large, nearly two inches long, with distinctive black and yellow stripes and reddish-brown eyes and legs. They are mostly solitary insects that nest in bare soil and along edges of flower beds. Hornets

Hornets, or bald-faced hornets, look much like yellow jackets. They have black and yellow (and occasionally white) markings. However, hornets are often longer and thicker than yellow jackets, and their sting is often more powerful.

Unlike yellow jackets, hornets do not scavenge, so they are less likely to show up at your favorite outdoor activities. And unlike cicadas, hornets prefer to build their nests high above ground, such as high in eaves and trees.

See These Insects Buzzing Around Your Home?

While some bees, wasps, and hornets are harmless, you might still have difficulty spotting the difference. If you worry about an insect infestation on your home or property, don’t hesitate to call pest control, just in case. A professional can help you safely remove the insects and protect your home and family.

The “Bite” on Mosquitoes: How to Keep Mosquitoes Out of Your Yard and Away from Your Skin

Written by Chem-Wise on . Posted in Blog

As a child, you may have read the children’s book Why Mosquitoes Buzz in People’s Ears. In this book, a mosquito lies to a lizard, which causes a chain reaction, eventually disrupting the entire animal kingdom. The story ends by saying that the mosquito continues to buzz in people’s ears to find out if everyone is still angry at him.

If this story were true, it may partially explain the anger many people hold toward mosquitoes. But we all know was have plenty of other reasons feel angry with them. Mosquitoes are especially annoying if they overpopulate your yard, ruining your chance to enjoy the outdoors. Let’s learn more about mosquitoes’ role in our ecosystem and how we can keep them safely at a distance.

What Is a Mosquito?

I’m sure you’ve seen-or received a bite from-a mosquito at some time in your life, but have you stopped to learn more about this interesting creature? Mosquitoes are midge-like flies (their name in Spanish literally means “little fly”).

There are more than 3000 species of mosquitoes, and only three species spread human disease. Surprisingly, most blood-seeking mosquitoes prefer biting horses, cattle, and birds rather than humans.

An adult mosquito lives 5 to 6 months. This doesn’t seem like a lot to humans, but for insects, it’s a long life.

The Danger of Mosquitoes

Mosquitoes seem bad enough simply because of the annoying, itchy bites they give people. The itchiness comes from your body’s reaction to the saliva the mosquitoes inject when they take your blood. But that’s not the end of the story-mosquitoes can spread all sorts of blood-borne diseases, like the following:

West Nile Virus: This disease isn’t as dangerous as you may think, as most people do not experience symptoms. However, 1 in 5 people will develop a fever, and 1% of people may develop a neurological disease.

Malaria: Thousands of people die from malaria each year, most of whom live in Africa. Malaria, a parasite-caused disease, causes flu-like symptoms.

Yellow Fever: Also causing flu-like symptoms, yellow fever is a dangerous virus. It can also cause muscle pain and even liver damage.

Chikungunya Virus: Chikungunya happens most commonly in the Caribbean, but it has also spread to many U.S. states. It causes joint pain but rarely proves fatal.

  • Dengue Fever: Like other mosquito-borne diseases, dengue fever causes flu-like symptoms and joint pain. In extreme cases, it can cause bleeding and low blood pressure.

Fortunately, the majority of mosquitoes will not infect you with a disease. But the more you can reduce or repel your mosquito population, the less likely you are to contract a mosquito-borne illness.

Mosquitoes Aren’t All Bad

Before we move on to strategies for eliminating mosquitoes, let’s cut the mosquito some slack. We’ve already noted that the majority of mosquitoes do not carry disease. But what about mosquito bites? It’s interesting to learn that that only female mosquitoes bite, and they do so to feed their children. So they don’t exactly bite you with malicious intent.

Still annoyed? Note that mosquito larvae serve as food for fish and other animals. Eliminating mosquitoes completely would disrupt the ecosystem.

How to Eliminate Mosquitoes

Despite their benefits, an overpopulation of mosquitoes is no fun to have in your yard. We’ve given you some tips for keeping them at bay:

Wear mosquito repellant while outdoors. Repellants contain substances such as DEET, SS220, and citronella oil. If you use DEET-based sprays, do not use it under clothing or on broken skin, and choose a product that contains less than 30% DEET.

If you plan to host an outdoor gathering, light citronella candles or torches to keep mosquitoes away.

Plant plants that naturally repel mosquitoes. These include basil, citrosa, lavender, lemon balm, and lime basil.

Wear long-sleeved shirts and long pants.

Stay indoors at dawn and dusk when mosquitoes will more likely bite.

  • Eliminate areas of standing area in your yard, because mosquitoes need water to hatch. These areas include flower pots, bird baths, ponds, and swampy areas.

If these methods do not keep mosquitoes out of your yard, call a pest control professional. A professional can eliminate the cause of the problem not only by removing adult mosquitoes, but by removing mosquito larvae. He or she will also provide a treatment that will keep mosquitoes from congregating in your yard.

You can use chemicals and traps yourself, but this can prove dangerous if you have not first consulted with a professional. A pest control professional has the training to use only environmentally friendly pest control methods that won’t harm nearby plant or animal life.

Stop those mosquitoes from buzzing in your ears! If mosquitoes have overrun your yard and destroyed your summer vacation, take steps to repel them or lower their population. If these steps don’t work, call a pest control professional.

Indian Meal Moths in Schaumburg, IL

Written by Chem-Wise on . Posted in Blog

The Indian Meal Moth is a very common insect found in stored products within the home and in stored grain on farms, in warehouses, and grocery stores. In the home, Indian Meal Moth larvae feed on any grain product (flower, cornmeal, oatmeal, etc.), seeds (including bird seed and dried beans), nuts, chocolate, dried fruit (such as raisins), and even dog food. These larvae often leave their food supply when they are ready to spin their cocoons and they may wander about in search of a suitable place to pupate. They are frequently found in unsuspected places because of this wandering behavior. Control of any stored food pest requires locating and eliminating infested item(s). All potentially infested foods should be checked. The insects may be in unopened boxes or containers. Infested items can be thrown away or salvaged by freezing for 1 week or heating in a 140 degree oven for 15 minutes. Empty and thoroughly vacuum clean cupboards or shelves holding infested items, paying particular attention to cracks and corners. Vacuum cleaning picks up hiding insects and spilled or infested material. Empty the vacuum cleaner bag after use to prevent re infestation. Insecticide sprays are not recommended for controlling insects in stored food cupboards.

Chem-Wise usually does not need to spray for Indian Meal Moths. The customer must first follow the following outlined steps, which in many cases will eliminate the problem:

  • Thoroughly clean cupboards with a strong cleanser: repeat this process two weeks later
  • After cleaning, thoroughly vacuum cupboards paying close attention to cracks and corners
  • Store pet food in air tight containers: throw out old food and clean the containers before adding a new bag
  • Store susceptible foods in seal able glass, metal, or heavy plastic containers

Treatment is really up to the homeowner, we do sell Pheromone Traps to customers with an ongoing problems. If you have any questions regarding stored product pests in the Naperville area, please call our office.

Pest Prevention in Chicago

It’s sad to say it, but winter is around the corner.  Anyone that had the pleasure of being in the Chicagoland area last winter is probably not looking forward to another long, cold, snowy winter.  Summer seemed to take forever to arrive and now it’s gone already.   I guess that is just how the story goes when you live in a four season state like we do.  The good news is that there are many things you can do as a homeowner that will help make living in your home this winter a little more tolerable no matter how cold it gets outside.  It’s one thing to wake up in the middle of the night cold, but it’s another to wake up cold and see a mouse scurry across your floor.  Below you will find tips that will help keep your home pest free and also might even save you money in the long run.

1.  Seal Up Entry Points.  This will not only make it tougher for pests to invade your home, but it will also prevent drafts and save you money on your gas and electric bills.  Repair any damaged screens or windows and make sure they are all properly caulked on the outside and the inside.  Apply weather stripping and/or door sweeps around all doors.  Use caulk to seal up any other holes or cracks you may have on the outside of your home.  Also, be sure to keep the garage door closed as much as possible.

2.  Clean Out Gutters.  Doing this will eliminate insects from nesting in your gutters and eventually invading your home.  It will also prevent a potential roof leak if water gets backed up on your roof from the gutters being clogged.

3.  Clean Up Yard & Relocate Firewood.  Leaves and brush should be picked up and properly disposed of (check with your local municipality for a brush/leaf pickup schedule).   Don’t forget to clean out your window wells also.  Ideally you should have window well covers installed.  Firewood and brush piles should be stored at least 2 ft away from your home.  In addition, try to avoid bringing firewood indoors until you are ready to burn it since many pests like to hang out in the wood piles.

4.  Eliminate Moisture.  Make sure you inspect your basement, crawlspace, bathrooms, kitchen, attic, and roof to be sure you do not have any water leaks or moisture content.  Not only will accumulation of water or moisture cause damage to your property it can also attract pests into your home.  To help eliminate dampness in a basement or crawlspace you can set up dehumidifiers to alleviate some of the moisture.  For any major leaks that you find, we recommend using a licensed contractor to make the necessary repairs.

5.  Remove Clutter.  Pests love cluttered conditions since there are so many places for them to hide.  Since wintertime can leave you stranded inside with nothing to do, why not go through your storage in your basement and garage and get rid of what you no longer need.  Doing this will help you be more organized and also eliminate potential hiding places for pests.

Hopefully you will find these tips useful and will enjoy a pest free winter.  If you do end up with any unwanted visitors inside your home be sure to give us a call and we will get a technician out to take care of the problem.  Stay warm and enjoy your winter!

Mouse Control in Chicago and Surrounding Areas

Written by Chem-Wise on . Posted in Blog

Ready or not, the Fall season is now upon us! This is the time of year we look forward to planning the upcoming holiday season and spending time with our families. Unfortunately this is also the time of year we will sometimes get the unwelcome house guests as well-the house mouse! Chem-Wise provides mouse control and rat control in Berwyn, IL and the surrounding Chicagoland area.

The house mouse is generally small and slender from 2-3 1/2″ long, weighing 5/8 to 1 ounce. Mice are excellent climbers and can be found anywhere from cultivated fields to basements to upper stories in a skyscraper.

There are a few simple things that you can do to make these critters feel unwanted, and prevent them from being attracted to your home.

1. Keep leaf debris away from the perimeter of your home.

2. Keep you firewood stacked as far from the home as possible.

3. Keep your grass seed, bird seed and pet food in sealed containers so that the mice do not have a food supply.

4. Strategically place the bird feeders as far from the house as possible.

5. Make sure all potential entry points are sealed. The most common areas are where the utilities such as the A/C condenser line, gas line, water spigots and electrical lines enter the house.

6. Reduce the overall clutter in the garage to reduce the potential harborage sites.

Following the simple “cultural practices” noted above you will greatly reduce the changes of having mice overwinter in your home this cold season.

If you are having problems with mice contact your local Chem-Wise office today!


Boxelder Bug Control in Chicago, IL

Written by Chem-Wise on . Posted in Blog

Battling Boxelder Bugs!

Boxelder bugs are one of the most common and widely distributed household pests in the Chicagoland area. These distinct red and black bugs are a nuisance to homeowners because they often gather in large numbers on the sides of buildings and on nearby ornamental plants and trees.

They enter homes through:

  • open doors
  • open windows
  • through cracks around sills
  • bellow siding

BIOLOGY: The favorite host for this insect is the Boxelder tree (Acer negundo) especially the female tree, which bears the seed pods. Boxelder bugs may also feed on trees in the maple family. Since these insects can migrate great distances, it is not practical to remove the trees in order to reduce their population for Boxelder bug control.

During spring Boxelder bugs can be seen emerging from hibernation sites. Females begin to lay eggs during April and May, depositing them around host trees. The development from egg to adult takes about 60 days.

In the fall, there is an increase in the number of insects on homes and structures as the Boxelder bugs look for suitable sites to overwinter. This is the ideal time to perform Boxelder bug control with exterior barrier treatments. By treating homes in late September and October the Boxelder bugs are prevented from overwintering.

Boxelder bugs overwinter in such places as:

  • basements
  • wall voids
  • crawl spaces

Although it is difficult to achieve 100% elimination of this pest, Boxelder bug control applications by Chem-Wise during October will drastically reduce the population and decrease sightings throughout the year. Contact your local office for more information or click here.
