Home / Rodent Guide / Rodent Season in Spring Hill, FL: A Month-by-Month Guide
In colder states, rodent season starts when the first frost pushes mice indoors. Florida is different. Rats and mice stay active all year here, but their pressure on homes still rises and falls with the seasons.

In Florida there is no true off-season for rodents, because warm weather lets rats and mice breed year-round. In Spring Hill, activity in homes tends to rise in fall and winter, when cooler nights and ripening citrus draw roof rats toward houses, and again during the rainy and hurricane season, when storms and high water push rodents into dry attics, garages and sheds.
Roof rats, Norway rats and house mice can breed many times a year when food and shelter are available. UF/IFAS Extension notes that roof rats reach maturity in a few months, so a small number of rats in an attic can become a much larger problem within one season. Instead of a single rodent season, Spring Hill homes see a few periods when pressure is higher.
Citrus and other fruit ripen through fall and winter, giving roof rats a reliable food source right next to many homes. Cooler nights also make warm attics more attractive. This is a common time to hear scratching in the ceiling, and to find hollowed-out oranges still hanging on the tree.
Rodents that moved in over winter are often raising young by spring. Activity can become more noticeable as numbers grow, with more droppings, more noise and new chew marks. Spring is a good time to seal the roofline after any winter activity.
Heavy summer rain floods burrows and low areas, and storms bring down limbs and damage soffits, vents and screens. Rodents look for higher, drier shelter, and storm damage gives them new ways in. Debris piles left after a storm also provide cover close to the house. Coastal areas such as Hernando Beach and Bayport feel this most.
As fruit starts to ripen and seasonal residents return, rodents that settled in quiet homes over summer are discovered. If a home sat empty for months, this is a smart time for an inspection.

Rodents are active all year in Florida. Pressure on homes usually rises in fall and winter, when fruit ripens and nights cool, and during the rainy and hurricane season, when storms push rodents into buildings.
No. Rats stay active through the summer. Heavy rain and storms can actually push more rodents toward homes looking for dry shelter.
Any time you find activity, but late spring and early summer are good times to seal the roofline before hurricane season, and fall is a good time to trim trees and pick up fruit before winter activity rises.
Call and tell us where you are and what you are hearing, seeing or smelling. A local rodent specialist can then set up an inspection of your attic, crawl space, garage and exterior.
