When are cockroaches most active?

It’s easy to assume cockroaches are infesting our homes all year round. While the cooler months may offer some respite, entomologist Graeme Smith says cockroaches can invade kitchens and industrial spaces at any time of the year. That’s because they like warm and humid places no matter what the weather’s like. The warmer months are their chief breeding season, however, so it pays to understand their life cycle. “When the weather gets cool, the cockroaches are much less active,” says Smith. “They almost go dormant, even though they don’t necessarily die out.”
