A surprise wasp nest on your porch or under the eaves isn’t just a nuisance—it can make stepping outside feel like a gamble. Wasps are especially active during warmer months, and once they find a good nesting spot, they’re likely to return. The key to avoiding this kind of trouble? Stop them from nesting in the first place. Let’s look at what attracts wasps, how to prevent them from building nests, and what to do if they’ve already claimed a corner of your home.
Why Do Wasps Choose Your Home to Nest?
Wasps aren’t picky, but they do have a few favorite conditions when it comes to settling down. If your home checks any of these boxes, it could be on their radar:
- Sheltered spaces – Think eaves, attic vents, porch ceilings, or tucked-away corners of sheds and garages.
- Readily available food and water – Trash cans without lids, sugary spills on the deck, or even a dripping outdoor faucet can do the trick.
- Peace and quiet – They’re looking for places with little foot traffic or disruption.
In Central Ohio, the nesting season usually kicks off in early spring. That’s when queen wasps start searching for a place to build. Getting ahead of them now can save you headaches later in the summer.
How to Tell If Wasps Are Starting to Nest
You don’t need to wait for a full-sized nest to appear before taking action. There are usually warning signs:
- Wasps flying in and out of the same small area repeatedly
- A small, papery bump appearing under a soffit or beam
- Buzzing activity around your windows, roofline, or light fixtures
These early signs often show up before the nest gets large or dangerous. The earlier you catch it, the easier it is to prevent a full infestation.
Simple Ways to Keep Wasps from Building Nests
Trying to figure out how to keep wasps away without turning your backyard into a chemical war zone? Here are a few steps that work—and won’t disrupt your everyday routine.
1. Seal Up Gaps and Entry Points
Walk around your home and look for cracks, holes, or vents without screens. Focus on:
- Window and door frames
- Siding joints and rooflines
- Vents near attics or crawlspaces
A bit of silicone caulk or mesh screening can go a long way in closing off areas where wasps like to sneak in and build.
2. Take Care of Trash and Food
Wasps have a sweet tooth—and a nose for leftovers. To keep them from showing up:
- Keep outdoor garbage cans closed tightly
- Rinse recyclables before tossing them
- Wipe down patios, grills, and outdoor tables after meals
It’s not just the big messes—tiny sticky spots or crumbs are enough to draw them in.
3. Remove Small Nests as Soon as You See Them
Spring is the best time to knock down a nest. When it’s still small—usually built by a single queen—it’s far easier and safer to handle. Just be cautious:
- Avoid spraying during the hottest part of the day when wasps are most active
- Wear long sleeves and gloves if you attempt removal
- When in doubt, call in a stinging insect pest control expert in Columbus
Getting rid of the nest early makes it less likely the wasps will rebuild nearby.
4. Try Natural and Store-Bought Wasp Deterrents
Some scents send wasps packing. Peppermint oil is a big one, but clove and lemongrass can help too. Mix with water in a spray bottle and apply it under eaves or porch ceilings.
Other options:
- Decoy nests: Since wasps are territorial, they’ll often avoid building near what looks like another colony.
- Commercial sprays: Some products are designed to keep wasps from starting a nest at all. Apply these before the season gets into full swing.
These tactics aren’t foolproof, but they’re great as part of a bigger prevention plan.
5. Keep Your Yard Clean and Tidy
Yard maintenance matters more than you might think when it comes to pest control. Here’s what helps:
- Trim trees and bushes so they don’t touch your house
- Remove fallen fruit, dead wood, and piles of brush
- Empty birdbaths, buckets, or anything that collects standing water
The fewer cozy hiding spots and resources you offer, the less likely wasps are to settle in.
When to Call a Pest Control Professional
DIY fixes work best early in the season or as a preventive measure. But once a nest is established—or if you’re seeing wasps inside the house—it’s time to call in the pros.
Here’s why:
- Wasps get aggressive when their nest is disturbed
- You might not eliminate the queen, which means they’ll just rebuild
- Store-bought sprays often don’t penetrate deep enough for larger nests

FAQs About Preventing Wasp Nests
 Peppermint oil, clove, and eucalyptus are natural scents that repel wasps. Mix them with water and spray problem areas regularly.
They can. If a nesting site worked once, it’s likely to attract new queens the following spring—especially if old pheromones or nest remains are still present.
They can be. Wasps are territorial, so hanging a decoy in early spring may help prevent new colonies from forming nearby.
Ideally, start in late March or early April, before queens begin nesting. That’s when prevention methods are most effective.
