Young rats and mice wander and seek food and new home sites. Summer Food and vegetation are abundant. Rats and mice are more common because of spring breeding and available food. Another peak in breeding occurs in early September as summer temperatures cool. Fall Natural food sources and vegetation cover diminish as the weather turns colder.
Rodents are relatively abundant and seek winter homes.
Rats and mice seek winter shelter inside buildings following the first cold spell each fall. Make sure that rodents are controlled during winter - and there will be fewer around to breed in the spring. This can help prevent a year of problems. Keep kitchens clean and food stored in secure containers. Where rodents are present, use traps or poison bait to eliminate them.
