What Pests Are Most Common in The Fall?

Fall brings about a delightful change in scenery with its crisp air and vibrant foliage. However, as the temperatures drop, it's not just humans who crave the warmth and comfort of indoors. While piles of fallen leaves provide temporary refuge, our homes offer a more attractive, long-term sanctuary for many pests. Even the most diligent homeowner can still find themselves battling a pest infestation as temperatures drop. Below, we'll go through the most common pests, signs that you have some unwelcome guests, and some prevention tips.

Top Five Most Common Fall Pests

Pests of all kinds can find their way into our home; however, certain pests are more active in the fall. Each of the following pests can become unwelcome guests as the leaves start to fall:

  1. Mice: As temperatures drop, mice seek warmth and food sources indoors, making homes an attractive refuge from the cold.
  2. Spiders: Autumn is the prime mating season for many spider species, leading them indoors to find shelter and establish territories.
  3. Rats: Like mice, rats move inside to escape cooler weather and find consistent food supplies that become scarcer outside.
  4. Ants: Preparing for winter, ants often invade homes in search of sustenance, storing up food before their dormant period.
  5. Cockroaches: Drawn to the warmth and availability of food, cockroaches infiltrate homes in the fall to avoid the chilly outdoor conditions and to have access to food and water.
