  • Biodegradable bait station for liquid ant bait
    Patent number: 10729121
    Abstract: A biodegradable bait station is disclosed that can be used with liquid baits targeting pest ants in urban, agricultural, and natural setting, which can overcome several limitations that most of other liquid bait stations currently experience. For example, instead of keeping a large quantity of liquid bait in a reservoir, a small amount, for example, 10-20 ml of sugary liquid bait with an insecticide, for example, boric acid, thiamethoxam, imidacloprid, will be contained in a biodegradable cylindrical container with one open end. The open end will be plugged with a piece of water absorbent polymer or gel, for example, polyacrylamide gel, sodium alginate. The water absorbent polymer or gel absorbs the liquid bait and expands inside of the cylindrical container so that it will function as a polymer “wick” to deliver a small amount of the liquid bait to foraging ants.
