In one sentence, describe what the following article is about:

This is easy to make and can be put in the corner of the room that has a wasp problem. For this trap, you will need: Scissors Empty plastic bottle (2L) Tape Bait (watered down dish soap) Be sure to do this carefully with your scissors. You can also use a razor blade if the scissors don't seem to be cutting through the bottle. If you want to add vinegar, it will still attract the wasps but won't attract bees. This is going to form your at-home trap. The wasps will be attracted to the bait, fly through the neck of the bottle, and get stuck in the bottom where they will die. If you wish to hang it, heat two ends of a wire and stick them into either side of the bottle and hang it once the wire is secure. If too many wasps die, they can make a sort of raft for other wasps to live on in the bottom of the trap.
Gather your materials. Remove the bottle cap and cut through the bottle a third of the way down. Place your bait in the bottom of the bottle. Invert the top third of the bottle and slide in into the base. Tape the two pieces of the bottle together and place it anywhere in the room. Be sure to empty your trap consistently.
