What Seasons Do Pests Commonly Invade the Home?

Written by Chem-Wise on . Posted in Blog

As a homeowner, you likely know that preparation is key when the threat of pests presents itself. Not only can pests impact everyday living, but certain insects and creatures cause damage to wiring and structural parts of the house. Knowing when to expect certain pests in the home helps you prepare for and prevent damage before the critters have already invaded.

Learn about what seasons common pests and insects may come into your home, and discover how an annual plan will help deal with the threat all year long.


As the winter thaws, the arrival of spring brings a number of new changes including emerging pests. Along with fresh grass and flowers sprouting from the ground, ants begin burrowing their way back to the surface.

And many ants don’t just want a nest in soil, as they often find their way inside of the house. One of the ants that may pose the biggest problems for your home is the carpenter ant. The ant digs through wood to create nests and homes, and the resulting damage can speak disaster for some homes.

Other ants that may appear in the spring include black ants and red ants. These ants may dig through various cracks and entryways in the home, invading areas like kitchens and bathrooms.

Other pests that may arrive in spring include both millipedes and centipedes. They will often seek out moist and dark areas of the home, including cabinets and closets. Pest management treatments in the spring help prevent the arrival of these insects as the months get warmer.


The arrival of summer brings on a whole new set of pests to deal with. Earwigs, also known as pincher bugs, begin to emerge in the summer months, especially in places with higher humidity.

While earwigs are a silent pest, one of the louder insects that may invade your home in the summer includes crickets. They make noise all throughout the day and especially the night, creating the sounds of a summer yard right inside your living room.

With all of the new pests, ants are also still a problem in the summer months. Additional treatment helps prevent the return of the insects, especially as nests hatch and populations grow around the exterior of your home.

An early summer treatment on your home will keep all of nature on the outside to enjoy, especially as insect populations grow and bloom during these months.


When fall arrives, the bug population dies down, but you still have plenty of pests to worry about. In the Midwest area, one bug that emerges often in the fall is the box-elder bug. These bugs have a long flat body and may often invade a home in large clusters. The reason for their presence in the fall is the colder nights. The bugs look for a warm and comfortable place to spend the late autumn and winter months.

Once the box-elder bug enters the home, the removal process becomes more challenging. Treating your home at the beginning of autumn is the best prevention step and will result in fewer problems for the future.

Spiders often follow the same track as a box-elder bug. Various spiders begin to make their webs in autumn, although many are present throughout the summer as well. An autumn treatment will help prevent the spider from turning your house into their winter vacation destination.

Autumn is often a time when larger critters look for warmer locations as well. The month of September is an ideal time for mice and rat treatment. If you’ve noticed mice in your home in the past, then the home will be prone to the critter returning and creating nests.

Mice are also known for chewing wires, so removing them from the home will ensure the safety of the home’s wiring. A number of treatment methods exist for the mice in your home, including pesticides, nest removals, and full home inspections. Mice can fit into the smallest spaces, so using proper pest management techniques will be the best method as opposed to physical barriers and traps.


While a number of winter pest prevention is doable in autumn, a variety of pests may still pop up in the winter months. Mainly some of the pests to worry about are bigger ones. Unused chimneys, attics, and crawlspaces could all be attractants to larger critters like squirrels and raccoons.

The larger size of these animals means they cause more destruction. The animals are louder, may cause more damage, and could end up in some of the main areas in the home. Blocking off areas and using multiple measures of prevention will help keep these animals from the home and also prevent them from breeding in the home as well.
