Many pests that cause infestations of buildings have behavioral and biological cycles that follow the seasons of the year. Understanding these cycles can help you to plan for the right schedule and type of pest control services that you need for your home.

Why Pests Infest Homes at Different Times of the Year

Just like the trees and flowering plants have cycles that vary across the seasons, so do the pests that are prone to causing residential and commercial infestations. The pests are affected by changes in the amount of daylight as well as the daytime and nighttime temperatures. Understanding these cycles can help you to arrange for the type of pest control in Las Vegas that can help to prevent future infestations from occurring.

Swarming Behavior

Swarming behavior is a common event that you may notice during the early spring. When the days begin to get longer and warmer, many flying pests will swarm in or near your home. Flying ants, bees and termites all perform this sort of behavior as a part of their reproductive strategies. The swarm involves reproductive individuals that are ready to establish new colonies. If you see a swarm, this is a sure sign of an infestation.


Many pests undergo hibernation after the end of their reproductive cycles. For most pests, hibernation takes place during the colder months of the year. Pests such as rats, mice and other rodents will nest or burrow indoors to conserve energy. Insects and arachnids like spiders and scorpions will find a dark and quiet hiding place to wait out the chillier weather.


Some insects go through a process of migration. This is most common with caterpillars, butterflies, beetles and moths. Some bat and bird species will also migrate, and they can be considered pests if they get into your house. Houses located in temperate areas may be an ideal resting space for pests on their migration. The pests may seek temporary shelter or try to find sources of food or moisture. Pest control services can stop the pests from making their way inside of the home or building.
