How It Works

The W·H·Y Trap has two chambers and three lures to catch 19 different species of insects. The top chamber is baited with two lures -- one of which is a solid contained in a vial, and the other a liquid mixed with water. The bottom chamber is baited with a liquid lure poured onto a cotton pad. Wasps, hornets and yellowjackets have two ways to enter: either through the top cap, or through the holes in the bottom cap.

Pet Safety

Our WHY Traps do not use any killing agents or poisons. The product relies on luring the pest insects to the trap where they cannot get back out. Eventually, the trapped insects will expire on their own. The heptyl butyrate and the butanol can be strong eye irritants and mild skin irritants.  If there is eye or skin contact, then wash thoroughly with clean water and if irritation persists then see a doctor.

Where To Hang It

The RESCUE! W·H·Y Trap can be used outdoors wherever there is a paper wasp, hornet or yellowjacket problem. We recommend the trap be placed at least 20 feet away from an outdoor activity area, such as a patio or deck. Generally speaking, the W·H·Y® Trap will capture more paper wasps near a house structure, and more hornets and yellowjackets near a natural setting of bushes and trees. It can be highly effective to place multiple traps around the perimeter of a yard or area where insects are entering. The trap should also be placed at least 20 feet away from a known yellowjacket nest.

The W·H·Y Trap is designed to catch a wide variety of stinging insects: paper wasps, hornets (including bald-faced and European hornets), and many species of yellowjackets — in total up to 19 different species. No need to guess the pest!
The trap uses a dual-chamber design and a triple-attractant formula to target 19 different species of stinging insects. The top chamber is filled with water—once insects enter, they can't escape and drown in the liquid. The bottom chamber uses the same powerful lure as our Reusable Yellowjacket Trap. Once yellowjackets enter, they can't escape and die from dehydration.
Place the trap outdoors and at least about 20 feet away from patios, decks, or areas of outdoor activity. This helps lure the target insects away from where people gather. Hang the trap at least 20 feet away from any known nests. If the trap is too close to a nest, the target insects are likely to ignore it.
Using the trap early in the spring increases the likelihood of catching emerging queens before they start building nests — this helps reduce overall population later in the season. The trap is also effective throughout summer and into fall for catching foraging workers.
No extra bait or food is needed. The W·H·Y Trap includes an attractant kit. Follow the instructions on the label to bait the trap and hang it in a suitable location.
This trap uses a combination of powerful, scented lures to draw the target insects. Once inside the trap, insects either drown or die from dehydration. No killing agents are used. Still, you should place the trap away from high-traffic areas and children or pets, and never use near food or feed storage.
The WHY Trap is made of durable plastic and is reusable season after season. Once the contents fill up or the attractant expires, you can clean out or empty the trap and refill with a fresh attractant to use again.
The included attractant supply lasts about two weeks under normal conditions; after that, or sooner if the trap becomes full or the liquid evaporates, you should replace the attractant for best performance. Refill attractant kits are sold separately.
If you haven't caught any insects after 24 hours, try moving the trap to a new location. Sometimes it can take some trial and error to find the best spot for your trap. If you're still not having luck after trying the trap in a new location, email us at info@rescue.com and we can help you troubleshoot.
Deploying the trap early in the spring increases the chances of capturing queen wasps and hornets before they have a chance to establish nests. This can reduce the overall stinging insect population later in the season, making the WHY Trap a useful part of a pest prevention strategy.
