As winter begins to wind down, many Kansas homeowners are surprised to notice increased rodent activity inside their homes. Scratching noises, droppings, or sudden sightings often appear when temperatures are still cold—but spring is approaching.

Late winter is actually one of the most active times for rodents, and understanding why can help you stop problems before they get worse.

Why Rodents Are More Active in Late Winter

Rodents don’t hibernate. As outdoor conditions fluctuate, they become more aggressive in their search for food, warmth, and nesting sites.

Late-winter activity is often driven by:

Depleted outdoor food sources
Fluctuating temperatures forcing rodents indoors
Established nests inside walls or attics
Increased breeding activity as spring approaches

If rodents gained access earlier in the winter, late winter is often when homeowners first notice the problem.

Common Late-Winter Entry Points

As homes shift and materials expand or contract with temperature changes, new gaps can appear.

Rodents commonly enter through:

Foundation cracks
Gaps around utility lines
Dryer and exhaust vents
Roofline and soffit openings
Damaged crawl space vents

Mice only need an opening about the size of a quarter to get inside.

Homes with multiple entry points often require professional inspection and exclusion services to fully resolve rodent activity. Learn more here:https://www.bugshockers.com/wichita-residential-pest-control/wichita-rodent-pest-control

Why Waiting Until Spring Can Make the Problem Worse

Many homeowners plan to “deal with it later,” but waiting can allow rodent populations to grow rapidly.

Risks of delaying treatment include:

Increased spring breeding
Additional structural and insulation damage
Higher health risks from droppings and urine
More difficult and costly removal later

Addressing rodents in late winter is one of the most effective ways to prevent larger infestations.

Why DIY Solutions Often Fall Short

Traps and repellents may reduce activity temporarily, but they rarely address the source of the problem.

Effective rodent control requires:

Identifying and sealing entry points
Safe removal of existing rodents
Reducing food and nesting opportunities
Ongoing monitoring

This is why professional rodent control is often the most reliable long-term solution.

Frequently Asked Questions

Why do rodents come inside more in late winter? Outdoor food becomes scarce, and temperature swings drive rodents to seek shelter indoors.

Can rodents cause damage even if I only hear them? Yes. Rodents can chew wiring, contaminate insulation, and create fire and health risks even if sightings are limited.

Is late winter a good time for rodent control? Absolutely. Treating infestations before spring breeding begins can prevent much larger problems.
