The answer to 'pest prevention season' is that there is no single 'pest prevention season', as different pests are active at different times of the year. However, there are certain times of the year when homeowners should be more vigilant about pest prevention and control.
In most regions, spring and summer are the prime seasons for many common household pests like ants, cockroaches, mosquitoes, and rodents. As the weather warms up, these pests become more active and start looking for food, water, and shelter in and around homes. Fall and winter also bring their own pest challenges, like overwintering insects, rodents seeking warmth indoors, and pests that feed on stored food and materials.
