I want to know if this works! It looks like a great simple way to deter wasps from taking up residence at your house.

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 lightweight, recycled polyester fabric, it has an integral hanging loop and measures 12" high. In our tests we found it deterred wasps, including yellow jackets, up to 20' away. You may need two or more to cover large areas.

A great alternative to conventional traps

Sometimes cleaning means prevention. Is it just me or do I just know lots of people with wasp problems?

This bag (that mimics the shape of a wasp nest) natually discourages wasps from setting up shop - they are territorial and will go elsewhere. Made from 100% recycled polyester. No pesticides!
