What are the most common pests in Madison, WI?

In Madison, pest activity is heavily influenced by cold winters, warm summers, high humidity, and nearby lakes and green spaces. The most common pests in the area include:

• Rodents (mice and rats): Rodents are among the most common pests in Madison, especially in fall and winter when they move indoors seeking warmth and food.
• Ants: Several ant species are common in Madison, including pavement ants and carpenter ants.
• Mosquitoes: With Madison's proximity to lakes, wetlands, and standing water, mosquitoes are an extremely common seasonal pest. They're especially prevalent after rain and during warm, humid conditions.
• Stinging insects (wasps, yellowjackets, hornets): These pests often nest near buildings, under eaves, in wall voids, or in the ground, creating potential safety concerns around homes.
• Cockroaches: Roaches can be a common pest in apartments, condos, and older homes where warmth, moisture, and food sources are readily available. They're most often found in kitchens, bathrooms, and basements.

What is the peak season for pests in Madison, WI?

In Madison, Wisconsin, peak pest season runs from late spring through early fall, typically May through September. However, many pests can be a concern year-round.

• Spring (March‐May): As temperatures rise and the ground thaws, ants become active around homes and buildings. Carpenter ants may be drawn to moisture-damaged wood, while other insects begin emerging as temperatures rise.
• Summer (June‐August): Summer is the peak season for pests in Madison. Mosquitoes are especially common due to nearby lakes, rainfall, and humidity. Stinging insects can become more aggressive as colonies grow, while ants, flies, and spiders are also active.
• Fall (September‐November): As temperatures cool, rodents seek shelter indoors. Occasional invaders such as boxelder bugs and stink bugs gather on exterior walls and enter homes to overwinter. Stinging insects may remain active into early fall and become more aggressive as resources become scarce.
• Winter (December‐February): Cold weather slows outdoor insect activity, but rodents remain active indoors where warmth and food are available. Spiders and other pests already inside homes can also continue to thrive.
