Kill wasps naturally with homemade bait. In winter, wasps are attracted to protein sources. Partially cooked hamburger, fish, chicken, or liverwurst attract foraging wasps. In spring, summer and autumn, wasps are more attracted to sweet, sugary food sources. Apples, grapes, sugar and vinegar water are effective at attracting wasps during these warm months. Homemade bait lures wasps to traps, where the wasps drown.
Make a depository for wasp bait. Using a razor knife, cut a clear plastic soda bottle just above the hip near the top of the bottle. Discard the bottle cap. Invert the top of the bottle and place inside the bottom of the bottle. Punch three holes equally spaced around the perimeter of the bottle using a hole punch or ice pick. Make holes large enough to insert wire or cording for a hanger. Set hanger aside until you bait the trap.
Observe the top of the bottle inverted into the bottom of the bottle. With a permanent marker, indicate on the bottle bottom the location of the bottle neck.
Punch a hole on the line indicated in the step above. Make the hole a tight fit for a drapery hook or piece of wire shaped into a hook. Insert the hook on the inside of the bottle.
Place a piece of meat securely on the hook. You can use chicken, liverwurst on stale bread or red meat.
Combine 12 oz. of water with 1/4-cup sugar and 1/4-cup vinegar. Pour the solution into the bottom of the bottle, making certain that the sweet solution does not reach the meat.
Replace the inverted bottle top and attach the hanger. Gather the wire or cord together at the top and twist the wire or knot the cord. Hang from a hook.
