As the warm weather sets in across Indianapolis, outdoor activities become part of daily life—barbecues, gardening, and relaxing in the yard. But warmer months also signal the return of stinging insects like wasps and hornets. While these insects play roles in the ecosystem, their presence near your home can lead to painful stings and even serious allergic reactions.

Wasps and hornets are especially dangerous because they’re territorial and will aggressively defend their nests. Knowing the early signs of a nest can help you take proactive steps before these pests become a bigger problem. At Trio Pest Control, we’ve seen firsthand how quickly a minor issue can escalate into a serious infestation. Here are the top five signs that a wasp or hornet nest may be lurking around your Indianapolis home.

1. Increased Insect Activity Around Your Home

One of the most obvious indicators of a nearby nest is a noticeable increase in wasp or hornet activity. If you see these stinging insects flying around frequently—especially around windows, doors, eaves, or your deck—it could mean a nest is close by.

Unlike bees, wasps and hornets are more aggressive foragers. You’ll often spot them hovering around garbage cans, gardens, or any area with food and sugary drinks. If they seem to be flying in a specific pattern or returning to the same location repeatedly, follow their flight path from a safe distance. It may lead you to a hidden nest.

2. Buzzing Sounds from Walls, Eaves, or Trees

Wasps and hornets are not quiet neighbors. If you’re hearing a low buzzing or humming noise coming from your walls, attic, or outdoor structures like sheds or garages, it could indicate that a nest is nearby—or worse, inside your home’s walls.

These buzzing sounds often increase during the hottest parts of the day, when the colony is most active. Don’t attempt to investigate too closely. A disturbed nest can result in a swarm of angry insects. If you're unsure, call Trio Pest Control for a safe inspection.

3. Visible Nest Structures

Sometimes, you may actually see the nest. Hornets typically build large, football-shaped paper nests in trees, under eaves, or on the side of buildings. Wasps (like paper wasps) create umbrella-shaped nests with open combs that hang from sheltered surfaces like porch ceilings, awnings, or attic rafters.

These nests start small but can grow rapidly throughout the summer, housing hundreds or even thousands of insects. If you spot a nest—regardless of its size—do not attempt to knock it down or spray it with over-the-counter pesticides. These methods can backfire, triggering an aggressive response.

4. Chewed Wood or Plant Material

Many species of wasps and hornets build their nests from a paper-like material made from chewed wood fibers. If you notice that wooden structures like fences, decks, or outdoor furniture have been gnawed on or appear weathered in patches, you may be seeing the aftermath of nest construction.

This sign often goes unnoticed, but it’s a clear indicator that stinging insects are active around your home. Check for small scratch marks or soft, weathered areas, particularly under railings and eaves where wasps prefer to nest.

5. Aggressive Insect Behavior

Wasps and hornets become more aggressive as their colonies grow. If you experience repeated attempts from these insects to chase you or buzz close to your face, this could be a sign you’re near a nest. Some species, like yellowjackets and bald-faced hornets, are notoriously territorial and will sting without much provocation.

If you notice that simply walking through your yard causes a swarm of activity, it’s time to take action. Avoid the area and consult a professional pest control service like Trio Pest Control immediately.

Why Professional Nest Removal Is Essential

Trying to remove a wasp or hornet nest on your own is risky business. These insects can sting multiple times, and their venom can cause severe allergic reactions. Additionally, store-bought sprays often only eliminate the outer layer of the colony, allowing the queen and workers to rebuild within days.

Professional pest control companies have the tools and training to remove nests safely and prevent reinfestation. At Trio Pest Control, we specialize in identifying the species, locating hidden nests, and applying targeted treatments that eliminate the colony without putting your family at risk.
