The answer to 'emergency pest control season' is that there is no single 'emergency' season for pests. Pest activity can spike at different times of the year depending on the specific pest and your local climate. However, some general trends can help homeowners prepare.
Many common household pests like ants, cockroaches, and rodents tend to be more active and seek shelter indoors during the colder fall and winter months. Mosquitoes and other summer pests are more prevalent in the warmer spring and summer seasons. Knowing when different pests are most likely to become a problem can help you take preventative measures and be ready to address any infestations quickly.
