Expert Statements
Emory Matts, Board-Certified Entomologist and Technical Service Manager at Terminix
“Several factors can influence where rodent pressure shows up from year to year. Weather, drought, development, population shifts, and the availability of food and shelter can all play a role. Dry conditions can push rodents indoors in search of food and water, while milder falls and winters can extend breeding windows and allow populations to grow before colder weather arrives.”

“Most homeowners don't think about rodents until they find evidence of them, and by then, the infestation may already be established. Fall is when rodents are most actively searching for a way inside. A mouse can fit through a gap the size of a dime, so even a small opening can become an entry point.”
