Pest pressure in Illinois
Illinois's climate is humid continental, with hot summers and cold winters. Illinois has a full four-season pest cycle — termites in spring, mosquitoes in summer, rodent intrusion in fall and winter. That climate profile is what drives the specific pest pressure IL homeowners deal with — and it's the reason pest control programs in Illinois look different than they do in colder northern states.
