The Exterminator’s Datebook: A Guide To Seasonal Pests

Exterminators see a lot of bugs each year, and many will tell you that they can set their watch based on the time year when certain pests start finding their way into homes. Throughout the year pests enter the home for different reason, such as in search of shelter during the winter.

By learning about when pests most frequently invade homes and for what reason you can be more prepared for them by the time they try to find their way into your home. Take some time to familiarize yourself with the following seasonal pests, and the reasons they enter homes.


Winter is one of the most common times for pests to enter the home, as many of them are incapable of withstanding the lower outdoor temperatures experienced during winter months. Boxelder bugs, beetles, ladybugs and many other pests frequently flee into homes once temperatures start dropping. This process is known as overwintering.

Large scale overwintering could take place without being noticed. Many pests hibernate for the winter, so once they’ve found their way into your home they will hide out inside of walls or other hard to spot places until spring arrives. As soon as signs of springs appear you’ll start to notice your overwintering guests as they scurry around your home in search of an exit. If a pest decides after arriving that your home is not a suitable place for overwintering they may make themselves known during an attempt to escape before winter ends.


Many pests are active in the spring, including termites, ants, stinging pests, moths and stink bugs. Many of these pests, particularly termites and ants, are swarming during the Spring months, meaning mating pairs are looking for a place to start a new colony, and such behavior is the first time homeowners know they have an ant or termite infestation.


Ticks, fleas and mosquitoes are all pests that bite and are most active during the summer. There are other common pests, like flies and mice, that are active during the summer as well. Many of these pests find their way inside of the home on pets as they travel in and out of the home. Fleas and ticks can be an annoyance to you and your pet, but they can be dangerous as well. Lyme disease, Rocky Mountain Spotted Fever, Anaplasmosis and Tularemia are all diseases that are commonly spread by ticks.


As soon as summer temperatures start to drop exterminators begin noticing a different set of pests around homes. Cockroaches, bed bugs, and ants are three of the most commonly spotted household pests in the fall. These pests primarily enter the home in search of food, and once they’ve made themselves at home they can be three of the hardest pests to remove.

Bed bugs are an especially tricky pest to remove, since they typically do not respond to sprays and baits like most household pests. Bed bugs find their way into the home on clothes and in luggage, most commonly following hotel stays. These pests were kept at bay from around the time of the second world war until less than a decade ago. Now bed bugs are one of the most common and fastest spreading pests in the United States.

If you notice signs of seasonal invaders get in touch with a pest control expert right away. Removing these pests on your own can be a very tricky job, and if not done correctly you could have a worse pest problem on your hand than you started with. Don’t wait for a full-scale infestation to occur before putting an end to this problem, call an exterminator at the first signs of pests in your home.
