Wasps are flying, stinging, insects which are predators of other insects. Only the male wasps aid in pollination. There are three types of wasps: parasitic wasps, solitary hunting wasps and social wasps. It doesn't matter what type of wasp you have spotted in your home; the same methods of finding and killing them apply. Wasps are attracted to cut meats, such as turkey, ham, fish or liver. Creating a trap for the wasp in your home is going to be the easiest and most effective way to find it and kill it.
Fill a 5 gallon bucket 3/4 of the way full with water. Add a 1/2 cup of dish soap and stir for 40 seconds.
Purchase a small piece of wire mesh screen from your local hardware store. You only need enough to cover the top of your bucket.
Cut a 2-inch hole in the center of the wire mesh screen with wire cutters.
Tie a string to the left of the hole to the screen. It should suspend 2 inches above the water in the bucket once the screen is placed on top of the bucket.
Tie a piece of turkey, ham, fish or liver to the other end of the string.
Place the screen on top of the bucket, centering the hole to the middle of the bucket.
Place this bucket trap in the room you have spotted the wasp before. Leave out for 24 hours. Do not disturb. The wasp will find the meat and not be able to fly back out of the bucket. It will then fall into the water and die.
