The RESCUE! WHY Trap refill is a specialized chemical maintenance kit designed to support the ongoing use of the WHY (Wasp, Hornet, Yellowjacket) dual-chamber station. Specifications indicate that this 8-pack provides a sixteen-week supply, with each set of lures designed to remain active for approximately fourteen days. The system avoids the use of neurotoxic pesticides, relying instead on a specific blend of pheromones and feeding stimulants to attract target species.
Features include a multi-part attractant delivery system:
- A primary liquid vial containing Heptyl Butyrate.
- A secondary solid-state lure for diverse species targeting.
- A water-soluble packet that activates a foaming agent in the lower chamber.
Practical realities of use suggest that the effectiveness of these lures is sensitive to high temperatures; in climates exceeding 95°F, the attractants may evaporate more quickly, potentially shortening the refill cycle to nine days. For the best results, the station should be placed approximately 20 feet away from known nests to ensure the scent trail remains clear for the insects to follow.
Designed to target 19 species of stinging insects without attracting beneficial honeybees, this refill kit provides a specialized alternative to general sugar-water baits.
If you find that your specific pest problem involves more aggressive ground-nesting varieties, you may want to compare this with a disposable bag-style trap designed for high-volume captures.
