A method for destroying a wasp nest, comprising:

• providing or offering a poison bait, wherein the poison bait has a sugar content (Brix) of 40 or more and less than 83, which increases palatability to wasps, wherein the sugar content (Brix) is a sugar refractometer reading of the poison bait, said poison bait containing an insecticide and one or more components selected from the group consisting of fructose, liquor, vinegar, sucrose, lactic acid bacteria beverage, and syrup;
• disposing the poison bait in an area at least 1 meter away from and within 5 meters of a wasp nest to let wasps eat the poison bait;
• thereby facilitating delivery of the eaten poison bait by the wasps to the wasp nest;
• and
• propagating the eaten poison bait to other wasps, thereby destroying the wasp nest,
• wherein the poison bait is stored in a container comprising a liquid-absorbing member, wherein the liquid-absorbing member contains the poison bait and has an upper surface side and a lower surface side along a vertical direction, wherein the liquid-absorbing member has at least one hole or recess extending from the upper surface side toward the lower surface side, said hole or recess having an opening sized for a single wasp's head to fit through, and
• wherein the poison bait contains fructose.
