Q: How does a decoy nest keep real wasps away?

Wasps are territorial, so this waspinator reads to them as a rival colony already holding the area, and they avoid building nearby instead of contesting the territory.

Q: Do I need more than one for a big yard?

Yes, a single decoy is sized for a small area, and larger yards or patios usually need two or more spaced around the space for full coverage.

Q: Will it work on yellowjackets too?

Yes, testing found it effective on yellowjackets as well as common wasps, deterring them from distances up to 20 feet.

Q: Why is mine losing its round shape?

A wasp deterrent like this one holds its shape better when the hollow interior is stuffed with plastic bags, which keeps the sides from collapsing in over time.

Q: Does it use any chemicals or bait?

No, it works purely through wasps' territorial instinct rather than any chemical repellent or bait, so there's nothing to refill or replace.

One of the easiest ways to discourage wasps from hanging around your porch, patio or picnic site is by using this simple mock wasp nest. Because wasps are territorial, they recognize the nest as a hazard to avoid.

Made from durable polypropylene, it has an integral hanging loop and measures 12" high. You can fill it with plastic bags to help maintain its shape. In our tests, we found it deterred wasps, including yellowjackets, up to 20' away. You may need two or more to cover large areas. A great alternative to conventional traps.
