Serving Eastern Iowa, Southwest Wisconsin, and Northwest Illinois – Including Dubuque, Platteville, Galena, and Beyond
As late spring warms the bluffs along the Mississippi River and your lawns and gardens burst into life, pest activity ramps up across our tri-state region. Warmer temperatures, spring rains, and blooming vegetation create perfect conditions for insects to emerge, forage, and build nests. At
Kramer Pest Control, we’ve seen it year after year: homeowners in Dubuque and surrounding communities suddenly notice increased bug activity around homes, decks, and yards.
Here’s your essential guide to the
Top 5 Bugs to Watch This Season, plus targeted prevention and safe removal tips for wasps and carpenter ants—two of the most common and concerning pests right now.
The Top 5 Bugs Active in Late May & Early June Across Eastern Iowa, Southwest Wisconsin & Northwest Illinois
- Carpenter Ants These large, black ants become highly active in spring as they forage for food and moisture. In our area, they often nest in damp wood around homes, decks, and trees. Look for large ants (up to ¾ inch) trailing along foundation edges or inside kitchens. They don’t eat wood but excavate it, causing structural damage over time.
- Wasps & Yellow Jackets Queen wasps emerge from overwintering and begin building small “starter” nests under eaves, porch ceilings, and in wall voids. By late May, these can quickly expand into full colonies. Paper wasps and yellow jackets are especially common in our region’s wooded and suburban areas.
- Ticks Deer ticks and lone star ticks peak in late spring. Tall grass, wooded edges, and trails around Dubuque, Platteville, and Galena make this a high-risk time for Lyme disease and other tick-borne illnesses. They latch onto pets and people during outdoor activities.
- Mosquitoes Standing water from spring rains leads to rapid breeding. These pests become a backyard nuisance exactly when families want to enjoy evenings outside. In our humid tri-state climate, they multiply fast near rivers, ponds, and poorly drained yards.
- June Bugs (May/June Beetles) & Early Lawn Pests These chunky brown beetles emerge in late May and June, often attracted to porch lights. Their larvae (grubs) feed on lawn roots, while adult beetles can damage young plants and trees. Aphids and other garden pests also surge with new growth.
Pro Tip from Kramer Pest Control: Early detection is key. Many of these pests are easier (and cheaper) to manage now before populations explode into summer.
Wasp Nest Prevention for Late May: Safe Removal Tips for Dubuque, Northwest Illinois & Southwest Wisconsin Homes
Late May is prime time for queen wasps to establish nests. Catching them early prevents painful stings and large colonies later.
Prevention Steps:
- Inspect your home weekly—focus on eaves, soffits, porch ceilings, door frames, and deck railings.
- Seal cracks and gaps in siding, windows, and foundations.
- Keep garbage cans tightly sealed and rinse recycling.
- Trim back vegetation touching your house.
- Remove standing water and avoid leaving sugary drinks or pet food outdoors.
- Consider installing fake “decoy” nests (wasps are territorial and may avoid areas with existing ones).
Safe Removal Tips:
- For small starter nests (size of a golf ball or smaller) at dusk or dawn when wasps are less active, use a long-reach wasp spray labeled for that use. Wear protective clothing.
- Never use a ladder near an active nest without professional help.
- Avoid swatting or disturbing nests during the day.
- Do not attempt removal if you have allergies, the nest is large, or it’s in a hard-to-reach spot. Call the experts at Kramer Pest Control for safe, effective removal using targeted treatments that minimize impact on beneficial pollinators.

Spring Ant Surge in the Midwest: How to Stop Carpenter Ants Before They Damage Your Home
Carpenter ants are one of the Midwest’s most destructive spring pests. They seek moisture and are drawn to homes with wood rot, leaks, or poor ventilation—common in older Dubuque homes and properties near wooded areas.
Signs of a Carpenter Ant Problem:
- Large black ants (bigger than pavement ants) indoors, especially near windows or baseboards.
- Sawdust-like “frass” piles near wooden structures.
- Rustling sounds in walls at night.
- Winged “swarmers” in spring (indicating a mature colony nearby).
How to Stop Them:
- Eliminate Moisture: Fix leaks, improve ventilation in crawl spaces and attics, and direct downspouts away from foundations.
- Remove Food Sources: Keep kitchens clean, store food in sealed containers, and take out trash regularly.
- Seal Entry Points: Caulk cracks around pipes, wires, and doors.
- Trim Trees & Remove Wood: Cut back branches touching your roof and clear woodpiles, stumps, or debris away from the house.
- Avoid DIY Baits Alone: These often treat symptoms but miss the main colony, which could be in a tree or wall void dozens of feet away.
Kramer Pest Control’s Approach: We locate and treat both parent and satellite colonies with precise, low-impact products. Early spring treatment prevents major damage and future infestations.
