New Berlin is a suburban community in southern Waukesha County, west of Milwaukee, known for keeping a significant amount of green space as it developed. Wooded properties, parkland, and open land run through the city, and the southwestern edge borders the lake-and-wetland country around the Muskego lakes. That green, lower-density character puts pest pressure here above the metro average for the pests that follow trees, brush, and water. Wooded residential lots put deer ticks within reach of many yards, and Waukesha County reports Lyme disease cases every year. The same cover draws wildlife, raccoons, squirrels, and skunks, toward attics, soffits, and the space under decks. Tree canopy across the city feeds box elder bugs and cluster flies that mass on warm walls each fall. The nearby lakes and wetlands add standing water for mosquitoes through the summer. Mice push into New Berlin homes from the surrounding open land once the cold sets in.

The pests New Berlin homeowners deal with most. Tap any one for identification and treatment details.
Deer Tick
A small dark tick that carries Lyme disease. The nymph stage is the size of a poppy seed and accounts for most human infections in the Upper Midwest and Mid-Atlantic.
Read moreHouse Mouse
The most common rodent in homes year-round. Small, fast, and capable of squeezing through a gap the width of a pencil, house mice nest inside walls and breed quickly.
Read moreMulticolored Asian Lady Beetle
The ladybug-looking beetle that invades homes by the hundreds each fall. It bites lightly, stains surfaces, and smells bad when disturbed.

Wisconsin's outdoor pest season runs roughly six months, but warming winters have stretched it at both ends. Treat this as a guide, not a fixed schedule.
When to call a New Berlin exterminator
Call a New Berlin exterminator about tick control in spring if your lot backs onto woods or open land, since Waukesha County reports Lyme cases every year and deer tick nymphs are most dangerous in May and June. For wildlife, a noise in the attic or soffit warrants a prompt call: raccoons and squirrels den to raise litters, and an operator checks for young before sealing. Mice are a fall and winter call, with exclusion sealing the lasting fix. For the box elder bugs, lady beetles, and cluster flies that mass on sunny walls in fall, a late-August exterior treatment is the effective timing. Mosquito programs are best set up in spring, before the nearby lakes and wetlands ramp up breeding. Wasp nests near a doorway warrant a fast call in late summer.
