Can be hung up or stood on a flat surface. Ideal for keeping wasps away from outdoor dining areas. Easy to empty. No chemicals or poisons. Instructions: Twist to remove the bottom from the top as shown on the box. Put a small amount of bait into the bottom. A few ounces of fruit juice or a few chunks or cut-up fruit will suffice. Twist the top back on, and place near the area to be protected. The tapered funnel design allows wasps to enter, but they cannot get out.
