A:  Yes as long as installed in the trap properly 

A:  Yes

A:  I live in Washington state. Rain doesn't seem to effect them. They do loose potency after a while and need to be replaced when you notice the yellow jackets loosing interst.

A:  I live in the northeast and we get a good amount of thunderstorms. My traps keep working throughout the spring and summer despite the heavy rain associated with these storms.

A:  Yes, no problem or issue with rain, as long as it is fixed right, I personally use outdoor zip ties so it never falls down.

A:  No, this trap only works for yellow jackets. If you want to trap wasps, you need the Rescue WHY (wasp,hornet,yellow jacket) trap.

A:  The Yellow Jacket is a type of wasp. I live in a rural area so put out 8 of these around my house each spring. They do attract lots of Yellow Jacket wasps and keep them farther away from my home. Not sure if you are inquiring about a specific type of wasp.

A:  no

A:  Thank you for reaching out in reference to our Yellowjacket Trap. Our Yellowjacket Traps will only attract Yellowjackets, the bait will not attract Wasps. For more information on our products that do work against Wasps please reach out to us at info@rescue.com

A:  I have used these for many years and only caught yellow jackets.  I don’t think they attract wasps.

A:  Be patient; they need to find it in their daily activities.

A:  Usually it happens fairly quickly. If what she is seeing is actually yellowjackets I would expect to see the trap producing results within 24 hours. I however wonder if what she sees flying around her flowers are native bees which would naturally be attached to her flowers. I have observed cases where I have had large amount of bees in the areas of our flowers and at first glance thought they were yellowjackets. However on further review I determined they were native bees since the yellowjacket trap located close by was not attracting them.

A:  I think it took about 4-6 hours or so for the first hornet to be trapped. Not as many this year as last but in 3 days each trap has about 6 insects. Installed 1 in the front and 1 in the back yard. Location might make a difference. I notice they fly around the house a lot so I hung on on the front porch rail and in the back yard off the rail around the deck both about 5-6 feet from the side of the house.,

A:  For me, the Yellowjackets came in waves. Some days nothing and some days 3-6 were caught. I had to play around with placement of the trap a bit. There was more activity in the fall. Nothing yet this spring. It’s too early it seems.

A:  In the garden now for 3 days, still no wasps caught in either trap. I think the attractant might be stale.

A:  I'm the original poster, and I also contacted Rescue (Sterling Int'l), which replied: Regarding your Yellowjacket Attractant Cartridges: None of our products expire as long as they are stored properly. You want to keep them stored in a dry location out of extreme weather conditions. Products purchased this year will be effective if you store them for future yellowjacket seasons.

A:  The cartridge is heat sealed into double (inner/outer) foil pouches. Unopened it should last a while. No expiry is presented on the package

A:  Package is tightly double sealed, year old attractant works just fine. I did not see any "use by" dates.

A:  I don't know if they have an expiration date, but I have been using them for years and I have found no difference in the effectiveness even after having them for over a year before I used them.
