What Customers Are Saying

Customers are sharply divided on this wasp trap's effectiveness. Many report dramatic success, capturing hundreds of wasps within days and noticing significant pest reduction around homes. However, an equally large group describes complete failure, with traps catching nothing despite visible wasp activity. Common issues include attractant vials that are unusable or lose potency quickly, yellowjackets escaping from the bottom chamber, and unintended capture of bees or ants. Some note placement and height affect performance. Overall, results vary dramatically by location and wasp species, leaving reviewers split between calling it transformative and labeling it a waste of money.

The best brand of traps if you have bees!

Would Not Recommend

I've had this trap at my house for the last year and it works so well. The refill is easy to replace and it actually works.

It works

Works great getting rid of the Wasps. The instructions didn't cover the wasp trap I had even though it was the same company.

The pouch can be a tricky to open.

Would Not Recommend

I found that the liquid/refill did not really help attract the wasps to the actual trap. I have used this twice now, and did not find this really helped with getting the wasps to the trap or ridding my outside patio of said wasps.

Beekeepers Bee-ware

Would Not Recommend

I bought two W-H-Y traps hoping to combat paper wasps. One is about 150 yards from my beehives and the other 200 yards. I have caught two wasps and numerous honeybees. As someone who sells and recommends bee safe products, I cannot, in good conscience, recommend these traps to beekeepers.

doesn't work

Would Not Recommend

This is the second time I've tried this trap and it doesn't work. Last time I got one single yellowjacket and several flies. This time the pests seem to avoid it at all cost. They hover around and fly away. Meanwhile, they SWARM my hummingbird feeder(part of the reason for trying the trap) which is nothing but sugar water. I've even removed the hummingbird feeder, but they won't touch the WHY trap. Really frustrating. I think I'll empty the trap and fill it with sugar water and see if I get bett...

Catch and release

Would Not Recommend

I bought one of these a couple of weeks ago. It has only been moderately successful. I've caught more with my modified pop bottle. Many wasps have escaped from the bottom cone. Fly around climb up the cone to the top go down the hole and escape out the bottom holes. There has to be a better design that will not allow them to go back down the inside of the cone.

Disappointed

Would Not Recommend

I bought this last week and followed directions carefully and hung it in my mother’s garage on her farm. Her garage has numerous wasps flying around. Went back 5 days later and not a single one was in the trap. Was very disappointed. $15 wasted.
