Why Does Tomah's Climate Attract Multiple Pest Species?
Posted by Mosquito Squad Plus
July 9, 2026
Tomah, WI, is a tight-knit community built around Lake Tomah. Families living here have reported a variety of pests coming during all seasons of the year. The whole region has deeply cold winters with wet, warm summers. While winters are known to kill off mosquitoes and ticks, the cold also pushes other pests to seek shelter inside. That changing climate pattern is one reason Tomah pest control often needs to address more than one pest at a time.
Moisture Helps Mosquitoes Multiply
Mosquitoes breed and thrive in water. Female mosquitoes can lay hundreds of eggs in the small amount of water in a planter base. Tomah has a rainy spring and a warm and rainy summer, constantly giving mosquitoes new places to settle. After a storm, water gathered in tarps or toys left out will attract mosquitoes if you aren't quick to dump the water.
Warm temperatures, combined with the rain, speed up the breeding process. Properties with dense shrubs, tall grass, tree lines, and damp corners may see more activity around patios and entryways, especially near dawn and dusk. Mosquito Squad Plus has several treatment options, targeting those resting and breeding areas, helping reduce mosquitoes by up to 85–90% for up to 21 days.
Boxelder Bugs Respond to Seasonal Shifts
Boxelders and stink bugs are commonly found in Tomah and across Wisconsin. They like the warmth, so as cool weather sets in, you will see them gather on the south side of the house and around windows and doors. Stink bugs are similar, moving into homes as the weather cools. Because their movement is tied so strongly to temperature, our treatments focus on exterior gathering points to prevent them from getting into hidden spaces.
Fleas Thrive With Warmth and Hosts
As pets and kids spend more time outside in the warmth, fleas are going to use them as hosts. Fleas need humidity to support their life cycles, while hosts (pets and wildlife) and cool shaded areas are gathering places for them. The tall grass, leaf litter, and pets moving in and out of the home all contribute to flea activity. It is hard to get rid of fleas once they are established outdoors without professional treatments. Mosquito Squad Plus treatments focus on the yard as a whole, including how best to treat your home.
Preventing Rodents in Tomah
As temperatures drop, rodents become more focused on warmth, food, and nesting sites. Tomah’s cold, snowy winters can make homes, garages, sheds, and commercial spaces more appealing to mice and rats. Small gaps around utility lines, garage doors, foundations, and vents can become entry points.
The weather also impacts rodents' food sources. During the spring and summer, they can get food from outdoor seeds, gardens, pet food, and even trash. In winter, these sources decrease, but once a rodent finds a reliable food source, they are prone to staying close and exploring ways to get in as the weather worsens.

The relatively reliable climate cycle in Tomah gives multiple pest species the ideal environment to breed and thrive. The wet, warm months will see a rise in mosquitoes, fleas, and gnats. Boxelder bugs react to cooling weather and sunny surfaces. Rodents respond to cold and shelter needs.
