Do decoy wasp nests work?

Updated on: 28th August 2026 

Quick overview

• Decoy wasp nests don't actually work — wasps will investigate and see through the fake
• Wasps are territorial but will still nest near other colonies, making decoys unreliable
• Some species nest in the ground, so hanging decoys won't deter them at all
• Professional wasp control is the safest and most effective solution when wasps move in

Barbeques and sweet-smelling drinks are a dinner bell for wasps. Swarming your backyard festivities and creating a frenzy is a wasp’s M.O. When they come around, family and friends abandon their plates, piled high with summer delights and umbrella-garnished fruity concoctions, as they try to avoid being stung by these relentless pests.

As a result of this all-too-common scenario, and out of desperation to find the ultimate solution, homeowners will try just about anything to safeguard their property from wasps, especially during the peak summer season. Therefore, it’s no surprise that the idea of a decoy wasp nest was conceived.

Do fake wasp nests keep wasps away?

It's a popular idea: hang up a decoy nest, and wasps will stay away, thinking the territory is already taken. The theory is based on the fact that wasps are territorial and won't build a nest near an existing colony. Sounds logical, but it doesn’t actually work.

While some homeowners report limited success early in the season, there's little scientific evidence to support the use of fake nests as an effective, long-term deterrent. Wasps are smart enough to investigate a potential threat up close, and a paper bag or plastic decoy won't fool them for long. Professional wasp control is a much more reliable solution.

What does a decoy wasp nest do?

The idea behind hanging a decoy wasp nest on your house or in your yard is that wasps that are scoping out the area will see it and avoid building nests in the area, thinking that another wasp colony has already established itself there. However, there is no proof that this tactic is effective or that it even works.

Do crochet wasp nests work?

Crochet wasp nests and knit wasp nests are handmade versions of commercial decoys, and they've gained popularity online. While they can look convincing, their effectiveness is no better than any other fake nest. 

Wasps rely on scent and colony behavior as much as visual cues, so a fabric replica is unlikely to fool them for long. They're a fun craft project, but not a substitute for real wasp prevention.

Why are decoy wasp nests ineffective?

• Different species of wasps don’t build hives in trees or under eaves; instead they build their nests in the ground.
• Once a wasp has built an established nest, they will not move. Hanging a decoy nest near an existing nest will do nothing.
• Not all wasps will build nests in isolation, meaning they are fine sharing an area with another colony, or a decoy wasp nest, for that matter.
• Wasps generally leave their nests at the end of the year, investigating other nests before deciding if they should find a different home. When they investigate the decoy wasp nest and find there are no wasps inside, they may not leave the area. There have even been reports that wasps have moved into decoy nests.

Effective wasp control

Wasps are territorial, can sting multiple times, and pose a real risk to anyone with an allergy. When a nest is on your property, the most effective step is to call in a professional.
