We seem to be getting a number of yellow jackets in our facility. The weather is changing daily from high in the 70s to low in the high 40s. The yellow jackets were rather small about a week ago and are more adult size now. For the most part, they seem to be docile and are easy to kill, but I suspect that may be for today only. What do you recommend? Also, we recently purchased light traps from you a few weeks ago and they are collecting a minimum number of yellow jackets compared to the population buzzing around the plant.
Typically, when Yellow jackets are inside of a building they are either nesting inside of a wall void or coming inside through cracks, open windows, or doors. When treating for Yellow Jackets it is always best to perform a direct treatment to the nest to ensure a quick and complete kill of the nest, and this application is best done at night when those Yellow Jackets are less aggressive. You can try to locate the nest by watching and observing their habits. If a direct nest treatment is not a possibility, then you can try baiting those Yellow Jackets. This can be done with our Alpine Yellow Jacket Bait Station Kit with Onslaught. 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. Mix your choice of bait with Onslaught, we recommend chicken or tuna. 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. Place a few ounces of bait in each station and hang the stations 5-6 feet off the ground and about 50 feet apart. Keep the stations out of reach of children or heavy traffic areas, but in areas where the yellow jackets can enter the stations. Light traps are a great way to control a variety of flying insects indoors, but they do do not work as well for yellow jackets and should not be used as the sole method to eradicate a yellow jackets problem.
