Madison's Wasp and Hornet Removal Experts
Madison Pest Control Experts with more than 15 years of experience offers expert wasp removal, hornet control, and yellow jacket extermination for homes and businesses throughout Madison, Wisconsin and greater Dane County. We locate the nest, treat it correctly, and remove it safely so you can use your outdoor space without risk.
A wasp or hornet nest close to a door, deck, play area, or high-traffic part of your property is not just an inconvenience. It is a genuine safety concern, particularly for children, pets, and anyone with a known allergy to stings. Wasps can sting repeatedly and become highly aggressive when they feel the nest is threatened. This is not a situation where a can of spray from the hardware store is the right answer.
We offer same-day and next-day service throughout Madison and Dane County for urgent wasp and hornet situations. Our quotes are upfront, our technicians are highly trained, and our work is backed by a satisfaction guarantee.
Why Wasp and Hornet Pressure Is High in Madison
Madison’s outdoor culture, extensive park system, and residential green space create ideal nesting conditions for wasps, hornets, and yellow jackets throughout the summer months. The city has one of the highest concentrations of parks and green space per capita among major U.S. cities, and that abundance of landscaped areas, mature trees, and dense vegetation provides exactly the kind of sheltered nesting habitat these insects seek.
Residential properties across Madison, from older homes with cedar siding and open soffits in the isthmus neighborhoods to newer construction with deck structures and landscaping on the west side, all present nesting opportunities. Properties near the lakeshores, along bike paths, and adjacent to Madison’s parks and natural areas see consistently higher wasp and hornet activity during late summer.
The outdoor dining, lakefront recreation, and event culture that defines life in Madison from May through September also puts residents and visitors in closer proximity to active wasp colonies. Yellow jackets in particular are drawn to food waste, outdoor dining areas, and garbage containers, which is why restaurant patios, outdoor events, and residential backyard gatherings frequently generate calls to us throughout the summer.
Why You Shouldn't Wait
A small nest in early summer can grow dramatically by late summer. What starts as a few wasps around a deck or doorway can eventually become a colony containing hundreds or even thousands of insects depending on the species.
The sooner a nest is identified and treated, the easier and safer it usually is to remove. A newly established nest in May or June is a straightforward job. The same nest left until August is a much larger and more defensive problem.
Why You Shouldn't Attempt Wasp Removal Yourself
Removing a wasp or hornet nest yourself can be dangerous. When disturbed, wasps release a chemical signal that causes the entire colony to defend the nest. Unlike bees, they can sting multiple times, making even small nests a serious safety risk.
Ground-nesting yellow jackets are especially hazardous because their entrances are often hidden until they are accidentally disturbed, triggering an aggressive swarm.
Our experienced technicians use the proper protective equipment and professional-grade treatments to safely eliminate nests. We identify the species, apply the right products for the nest location, and follow a proven treatment process that removes the colony while minimizing the risk of stings and future activity.
Wasp and Hornet Species We Treat in Madison, WI
Bald-Faced Hornets
Bald-faced hornets are large, black and white stinging insects that build the distinctive gray, papery aerial nests that many people associate with hornets. Nests are typically found attached to tree branches, under eaves, on siding, in shrubs, and on utility structures. A mature bald-faced hornet nest built through the summer can reach the size of a basketball or larger and contain several hundred workers.
Bald-faced hornets are highly defensive within roughly three feet of the nest and will attack without significant provocation if they sense movement or vibration near the structure. Nests in trees close to play areas, along fence lines, or attached to the exterior of the home near doors and windows are a significant safety concern. We treat bald-faced hornet nests at dusk when worker activity is lowest, confirm elimination, and physically remove the nest structure.
Paper Wasps
Paper wasps build open-comb, umbrella-shaped nests that look like honeycomb without a paper covering. They attach nests to eaves, soffits, door frames, window frames, deck railings, and under patio furniture. They are less aggressive than yellow jackets or bald-faced hornets but will sting if the nest is disturbed or if they feel cornered.
Paper wasp nests are smaller than hornet nests, typically holding 20 to 75 adults, but multiple nests on a single property are common. Older Madison homes with wood soffits, cedar siding, and open trim gaps provide numerous sheltered attachment points. We treat and remove paper wasp nests and advise on the structural conditions that make a property consistently attractive to them.
Yellow Jackets
Yellow jackets are the most aggressive stinging insect we deal with in Madison and the species most likely to be involved in a serious stinging incident. They are small, roughly 12 to 15mm, with bright yellow and black banding, and are frequently mistaken for bees. Unlike bees, they are predatory, highly defensive of the nest, and capable of stinging multiple times.
Yellow jacket colonies grow steadily from spring through summer. A queen that begins a colony with a handful of workers in May can preside over a colony of 3,000 to 5,000 workers by late August, which is when the majority of stinging incidents occur. Colonies nest in the ground, inside wall voids, in attic spaces, under decks, and in hollow trees. Ground nests are particularly common in Madison’s residential lawns and landscaped areas.
Signs of a Yellow Jacket Nest
- Consistent wasp traffic entering and exiting a single point in the ground, a wall, or a structure
- Wasps hovering low over a specific area of lawn or landscaping
- Unexplained stinging incidents while mowing, gardening, or walking in the yard
- A papery nest visible inside an attic, shed, or enclosed deck structure
How We Treat Yellow Jackets
For ground nests, we apply an appropriate insecticide directly into the nest entrance at the optimal time, ensuring the product reaches the colony and the queen. For nests inside wall voids or structural cavities, we assess whether direct void injection or an exterior perimeter treatment is the correct approach based on the nest location and construction type. We confirm colony elimination before closing out the job.
Our Wasp Removal Process
Step 1: Nest Location and Species Identification
We locate the nest or nests on the property and identify the species. Location and species determine the treatment method. A yellow jacket nest in a wall void requires a different approach than a bald-faced hornet nest in a shrub three feet from the back door. We confirm before we treat.
Step 2: Targeted Treatment
We apply the correct product for the species and nest location, timed to maximize effectiveness and minimize risk. Aerial nests are treated at dusk when workers have returned to the colony. Ground nests are treated with direct application into the nest entrance. Void nests are treated through the exterior with appropriate void injection equipment. All treatments are applied with full protective equipment.
Step 3: Nest Removal
Once colony elimination is confirmed, we physically remove the nest structure where accessible. Leaving an old nest in place can attract new queens the following season looking for an established structure to reuse, and in the case of wall void nests, can create odor and secondary pest issues as the nest material decays.
Step 4: Prevention Advice
We identify what is attracting wasps and hornets to your property and advise on the specific conditions that should be addressed. Common factors include open soffits and trim gaps that provide nesting access, food waste and outdoor dining areas that attract yellow jackets, and landscaping features that provide sheltered attachment points for aerial nesters. Long-term prevention is part of every job we do.
Commercial Wasp Control in Madison
Restaurants with outdoor seating, event venues, food service operations, and commercial properties with high foot traffic cannot afford to leave a wasp or hornet problem unaddressed.

We work around your operating hours, treat nests with minimal disruption to your business, and document every service visit.

Frequently Asked Questions
Q1. Is it safe to leave a wasp nest alone if it is not near an entry point?
It depends on the species and the location. A small paper wasp nest at the far end of a property away from regular foot traffic may not require immediate treatment. However, yellow jacket and bald-faced hornet colonies grow through the summer and a nest that seems manageable in June can present a serious risk by August when colony populations peak. We recommend getting any active nest inspected and making a treatment decision based on the species, size, location, and proximity to people and pets rather than assuming distance makes it safe.
Q2. I sprayed a wasp nest and now there seem to be more wasps. What happened?
This is a common outcome with partial or incorrect treatment. When a colony is disrupted but not eliminated, surviving workers become more aggressive and nest activity often appears to increase as workers repair damage and protect the queen. With species like yellow jackets that nest in wall voids or the ground, incomplete treatment can also cause the colony to relocate deeper into the structure, making follow-up treatment harder. If a prior treatment has not resolved the problem, call us. We assess the situation and treat what is actually there.
Q3. When is the best time of year to deal with a wasp nest in Madison?
The earlier in the season, the easier and lower-risk the treatment. A newly established nest in May or June contains far fewer workers than the same nest in August at peak colony size. That said, we treat nests at any point in the season. If you discover a nest in late summer, do not wait until next year. Yellow jacket colonies die off over winter but the nest location is often reused by new queens the following spring, and a nest inside a wall void can cause additional issues if left in place over winter.
Q4. Are your wasp treatments safe around children and pets?
Yes. We use products appropriate to the species and situation, applied with precision to the nest structure rather than broadcast spraying around the area. We advise you on re-entry timing for treated areas, which is typically short, and we do not leave products accessible after treatment. For households with young children or pets that spend significant time in the treated area, we walk you through any specific precautions that apply before we finish the job.
Q5. How much does wasp removal cost in Madison?
Cost depends on the species, the number of nests, the location and accessibility of the nest, and whether it is inside a wall void or structural cavity versus an accessible exterior location. A single accessible paper wasp nest is a straightforward job. Multiple yellow jacket nests, a large bald-faced hornet nest in a difficult location, or a colony inside a wall void involves more time and equipment. We inspect the situation and give you a clear upfront quote before any work begins.
Q6. How quickly can you remove a wasp nest?
In many cases we can provide same-day or next-day service throughout Madison and Dane County. Once on-site, many accessible nests can be treated during the initial visit. More complex situations involving wall voids, multiple nests, or difficult access locations may require additional follow-up. When you call, tell us where the nest is located and what you have observed and we will give you a realistic timeline for your specific situation.
