Alpine Yellow Jacket Bait Stations are an intuitive, easy and effective way to control Yellow Jackets around your home. Just one kit will provide you with enough product to treat Yellow Jackets year after year without ever having to buy another station, trap or insecticide. Each kit contains four reusable bait stations with hanging strings and one pint of Onslaught insecticide concentrate, the only insecticide labeled for Yellow Jacket baiting. You use the stations by placing a mixture of tuna or other food attractant (see below for examples) with a small amount of onslaught insecticide in each Alpine bait station. The stations are then hung around the outside of the home, out of reach of children, but accessible to yellow jackets. The Alpine bait stations will attract the stinging insects where they will contact, ingest and spread the insecticide, eliminating the yellow jacket problem sometimes within just a few days. Additional Alpine bait stations are sold separately.
There are several species of yellow jackets that are not scavengers and would not be attracted to the stations. We recommend trying out a few baits without the Onslaught before using the kit to ensure the species you are treating will take to a bait. A few recommended baits: raw chicken pieces, raw fish, canned tuna, cat food, or fruit
Alpine Yellowjacket Bait Stations are designed and labeled for use with Onslaught microencapsulated insecticide. When used together, they are the perfect combination for controlling yellowjackets (also commonly called meat bees) around residences, restaurants, resorts, campgrounds, zoos and other areas where humans or animals are harassed by yellowjackets.
Onlsaught insecticide is the only insecticide with an EPA approved label for yellowjacket baiting.
How to use the stations :
STEP 1. We recommend testing a few types of bait before using the stations. Recommended food baits incude raw chicken pieces, raw fish, canned tuna, or cat food. Raw chicken pieces or tuna tend to work the best.

STEP 2. Mix your choice of bait with Onslaught. You only need a very small amount of Onslaught for the bait to be effective. We recommend mixing 1/4 teaspoon of Onslaught per 12 oz. of bait.
STEP 3. Place a few ounces of bait in each station and hang the stations outside around your home 5-6 feet off the ground and about 50 feet apart. For example, you could hang the trap from a tree limb. Keep the stations out of reach of children, but in areas where the yellow jackets can enter the stations.
Poison bait is the best control, but not Onslaught
By Neal on 12/14/2014
I have had excellent success for 10 years with baited yellow jacket traps, which have reduced my backyard yellow jacket problem almost to nil here in the SF Bay Area. I switched from other microencapsulated insecticides to Onslaught when the latter became registered for the purpose. I had mixed results with Onslaught -- better than not baiting (or using traps), but yellow jackets were still an annoyance when we were eating outside. Then I read a UC Riverside study (http://www.pestboard.ca.gov/howdoi/research/2009_yellowjacket.pdf) that reported that "The only registered bait (Onslaught®, microencapsulated esfenvalerate) was not effective as a bait toxicant against the western yellowjacket, V. pensylvani". They found that fipronil was the most effective, at a dosage level of only 0.025% in bait such as chicken or fish. Note that fipronil products such as Taurus SC are not listed for this purpose (i.e. the label does not officially say that it is OK in a yellow jacket bait).
I tried the water-filled bag traps from my local garden store (the bags with an attractant where the yellow jackets crawl in but can't find their way out), and although the traps seemed to accumulate a lot of yellow jackets, my problem persisted. I found this product had been mentioned by a professor from UC Davis and decided to give it a try. I tested several kinds of bait and found they liked fish/shrimp cat food. I mixed a half-recipe, only 6 oz to start out and replaced it after 2 days. After 4 days the yellow jackets were gone. The bait stations are a little messy (and smelly!) to clean out afterwards, but I can't argue with the effectiveness. My wife and I can sit in the backyard again. As was mentioned in the FAQ, it can be a challenge to thoroughly mix so little poison with the bait. Using cat food helped because it was smooth and not lumpy. I also used a little extra water: I added the poison to a teaspoon of water, stirred, then carefully sprinkled the poison all over the bait, then thoroughly mixed for several minutes. So little poison is used, the supply should last for years. I give the product 5 stars for effectiveness but 3 stars for the care needed in mixing the bait, and the messy cleanup. 4 stars overall. I definitely recommend this product and will absolutely use it again next year.
I found the best way to use this product is as follows: Each morning make up bait by using plastic fork and spoon on paper plate. Place (4) 1/4 to 1/2 tea. of fancy feast salmon cat food on a paper plate. Using a medicine dropper, place on drop on each. Use the plastic fork to work it through and turn it over. Place each one in the bait station. Take them up at dusk when the bees have stopped working. Replace with fresh each morning. It took us about three weeks to get rid of yellow jackets under a deck that is close to the ground. We had a very large nest and maybe even two or three nest. Short of taking the deck apart there was no way to get to them. Next year I will use onslaught at the first sign of yellow jackets.
After trying everything else we could buy locally to get rid of our yellow jacket problem, we tried Alpine's kit. It seemed expensive, but you get a multi-year supply with it. It really works. Within three days, the problem was solved.
What is the active ingredient that kills the yellow jackets? Will Onslaught harm honey bees?
Onslaught contains the active ingredient Esfenvalerate. Like most other insecticides Onslaught will kill honey bees if they come in contact with the product. If you use protein based food baits such as chicken, cat food or tuna you will greatly reduce the chance that honey bees will be attracted to the bait stations and contact the Onslaught.
Has anyone tried combining Onslaught with an Attractant?
I am having a hard time getting the YJs to take the bait. Any ideas on how much is actually required to destroy the nest?
The nutritional needs of yellow jackets change periodically. During the early part of the season yellow jackets are mainly looking for proteins such as fish or chicken. They will usually forage for proteins first, while they are feeding their developing yellow jackets back at the nest, and this is the best time to bait for them. Using protein baits will also help deter honey bees from entering the bait stations (honey bees are on the decline and it is best avoid harming them whenever possible). During other parts of the season yellow jackets are looking for carbohydrate or sugary foods like soda, beer or fruit juice to help maintain energy levels. We recommend that you put out a couple of different protein baits (fish, chicken) and a couple of different carbohydrate baits (cola, fruit juice) without adding the Onslaught. Leave the bait out for a day or two and see which bait the yellow jackets are attracted to. Once you see which bait they like, then you can add the Onslaught to the mix and put out the bait stations. Be sure to use the recommended usage rate of 1/4 teaspoon of Onslaught per 12 oz. of bait to avoid making the bait repellent to the yellow jackets.
Does this product kill only the Yellow Jackets that come in contact with the bait?
Does this product kill only the Yellow Jackets that come in contact with the bait?
Can it kill the queen if the Yellow Jacket exposed to Onslaught returns to the nest?
When the yellow jackets take the bait that has been mixed with the Onslaught, they take the bait back and feed others in the colony including the queen, killing the entire colony. We recommend trying several different baits such as jelly, water packed tuna, wet cat food, raw chicken, fresh fish or cola. This will help you determine what the yellow jackets are foraging for and then following the directions included with the Yellow Jacket Kit, you can add the Onslaught to the bait.
How do you effectively mix 1/4 tsp of Onslaught with 12 oz of chopped meat?
I have little faith that my bait will be evenly mixed with such a small amount of a rather thick poison. How to do you attack this problem? I am thinking of diluting the poison in about 1 oz of water and then mixing with the bait.
It does not take much Onslaught for it to work. You can take a small paint brush and paint it on the meat and then discard the paint brush or any other similar method. You can mix the onslaught with water as well. That should still get the job done and does make it a little easier to apply to all the meat.
Does the Onslaught and the Alpine Yellow Jacket kit work on "paper wasps"?
I have a large problem with "paper wasps" which are
different from the "traditional" wasp.
The Onslaught that comes in this kit will kill just about any type of wasp if they make contact with the product. The idea behind this kit is that you mix the Onslaught with a food item and wasps take the food item back to their nest and share it with the other wasps, killing the colony. If you have a type of wasp that does not take bait, then the kit would not be very effective. You can set out a few different food items to see if the wasps are attracted to them. If the wasps are attracted then you can use the kit successfully. If the wasps are not attracted to the food, then you should consider just spraying an insecticide such as Onslaught topically to areas where there has been wasp activity. Here are a few recommended baits: raw chicken pieces, raw fish, canned tuna, cat food, or fruit juice. Raw chicken pieces or tuna tend to work the best.
