Do your treatment at night. Yellow jackets are similar to people in that they “go home” at night. One more point to mention – under no circumstances should you attempt to kill yellow jackets by pouring gasoline or other generic chemicals into the nest. Doing so will poison the ground, killing both plants and animals.Click to see full answer. Similarly one may ask, what kills Yellow Jackets instantly?Treat the nest with pyrethrum aerosols such as Stryker 54 Contact Aerosol, PT 565 or CV-80D. Pyrethrum forms a gas which will fill the cavity, killing the yellow jackets on contact. Wait until the aerosol is dry, and then dust in the opening with insecticide dusts such as Tempo Dust . how much gas does it take to kill yellow jackets? just 8 ounces of gas will kill the whole nest of yellow jackets and from my experience is the best thing for them. In this regard, how do you get rid of yellow jacket gas in the ground? Wait until dusk as they are less active. You wait until night when they all go in the nest. Pour gas in the hole. Kills them all.Can you drown out a yellow jacket nest?Answer. Yes, Gary; ANY firm that will vacuum them out of the ground. Toxic insecticides are useless in this situation, as the massive underground nests of these hornets are of a design that sheds liquids off to the sides. (Which explains why they don’t all just drown in the first heavy rain.)
