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.
FAQs
What pests does the W·H·Y Trap catch?
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!
How does the W·H·Y Trap work?
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.
Where and how far should I hang/place the trap for best results?
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.
When is the best time of year to use the W·H·Y Trap?
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.
Do I need to provide extra bait or food — or is the trap ready to use?
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.
Is the W·H·Y Trap safe to use around people, pets, and beneficial insects (like honey bees)?
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.
Can the W·H·Y Trap be reused, or is it disposable?
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.
How often should I refresh or replace the attractant?
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.
What should I do if I still see wasps, hornets, or yellowjackets around after installing the trap?
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.
Does the W·H·Y Trap help prevent nests from forming in the first place?
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.
