The answer to 'cockroach season' is that cockroaches can be a year-round problem, but certain times of the year tend to see more activity and infestations. Cockroach populations typically peak during the warmer months, often in late spring and summer. This is because cockroaches thrive in warm, humid environments and their breeding cycles are influenced by temperature.
During the warmer months, cockroaches become more active, seeking out food and water sources inside homes and buildings. They may also be drawn to areas with clutter, moisture, and organic matter that can provide them with shelter and sustenance. As the weather cools in the fall and winter, cockroach activity may decrease, but they can still remain active and continue to breed indoors.
