In Milwaukee, there is a wide variety in the seasons, and when they change, you can count on pest populations changing. Some pests will be more common during certain times of the year than in others, and it can be important to know when you are more likely to see them around.
Some of the things that dictate which pests are more common during certain times of the year include:
- Temperature levels
- Humidity
- Breeding grounds
- Food availability
By knowing which pests will have higher populations during the different seasons, you can be ready for them when they show up. This can help you prevent an infestation and keep them out of your home or yard.
Spring
During spring in Milwaukee, there is a lot of heavy vegetation and animal life. After the snow has melted and the sun comes out again, you will start to notice a lot of natural activity in your yard or garden. This is a fertile time for the earth, and all animals will be out more often looking for food.
Ticks hide in tall grass, which starts to sprout in the spring in Milwaukee. They will use these hiding places to latch onto people or animals and feed off them.

Ants start to swarm in the spring and will use this time to build their colonies under or around your home.
Summer
Summer in Milwaukee is very humid and warm. This is a perfect environment for all kinds of insects and other pests. You will be more likely to see insects around your yard or any place where people are gathered, like a barbecue or picnic.
Mosquitoes thrive in the warm, wet environment of summer. Any summer rains or irrigation will leave stagnant water, which is where mosquitoes lay their eggs.
Spiders use the high population of flying insects during the summer as feeding time. They will weave their webs in high-traffic areas hoping to find a meal.
Fall
Fall in Milwaukee is very mild, but you may start to notice cooler temperatures. This is also when vegetation will start to fall on the ground and rot or ferment, creating food for all kinds of insects and other pests.
Stink bugs will gather in the sunny areas of your home, trying to catch any warmth they can find. While they are not dangerous, they will release a foul odor if they are squished.
Beetles use the fallen vegetation of autumn as food and will be more likely to be found in your yard during the fall in Milwaukee.
Winter
Winter in Wisconsin can be very cold with large amounts of snow. When this happens, you will start to see more insects and rodents in your home, looking for places to hibernate or simply live until the snow melts and the weather gets warmer.
Rodents will be more likely to be inside your home during the winter in Milwaukee. They will use the walls and hidden spaces of your house to make their nests and hide.
Boxelder bugs look for shelter in the winter and will be generally found inside your home in the late winter as they come out from their hiding places to look for food and get ready for spring.
