How to Make a Wasp Trap

Bait the trap. It should not reach the opening of the bottle––the wasps should have to completely enter the trap in order to access the bait. You can also do this before you attach the two pieces together. Some bait ideas include:

Meat – This is the best choice in the spring and late winter because wasps are making nests and laying eggs, so they’re searching for high protein food; you may even catch a queen this way, in which case the wasps will relocate their nest.

Dishwashing liquid and water
Mashed grapes
Sugar and lemon juice
Kokanee beer or coolers
Sugar and water
Sugar and vinegar
1 tsp liquid laundry soap, 1 tsp sugar (to attract them), and water – if they do get out, they will still die from the laundry soap
Soda (lemonade, etc.) that has lost its fizz. This way it can still be of use. Add a few drops of washing up liquid to help break the surface tension of the soda.
