Yellow jackets are an ever-present nuisance around many homes in the summer months. With the TERRO Yellow Jacket Trap, you can attract and trap yellow jackets that pester you outdoors. The bait works by luring yellow jackets into the trap. They go in expecting a treat, and find they are unable to leave. For your convenience, the TERRO Yellow Jacket Trap is incredibly easy to use. Simply empty the included bait pack into the trap, add warm water to the fill line, and swirl to mix. Hang the trap on a tree branch, stake, or other suitable hanger. Traps should be hung in the late evening or early morning when yellow jackets are not active. Place in calm, sunny areas about 25 feet from activity areas for the best results. TERRO Yellow Jacket bait contains no chemical insecticides so you can use the trap with peace of mind. If needed, this trap can also be used with a supplemental bait as yellow jacket species and diets may vary. Recommended supplemental baits include lemonade, grenadine, fruit-flavored soda, fruit, fruit juices, beer, or sugar water. When the trap is full, it can be emptied and re-baited for continuous trapping.
