Yellow jacket colonies are started in the late spring or early summer when the queen sets up small nests to produce a new population of workers. You can prevent this development by looking for small nests that may be hanging under awnings, railings, doorways, or nooks outside your home. Knock down the nests with gloved hands or a large stick and promptly step on them to kill the egg cells inside.  The queen is usually the only mobile resident of her nests in the late spring and early summer. Once nests are larger and worker wasps start emerging from them, it will be too dangerous to destroy them this way. Yellow jacket nests are round, paper-like, and have a small entranceway at the bottom. Approach yellow jacket nests at dusk, when the wasps are no longer active. Sprinkle carbaryl, a powder pesticide, onto a cloth or old paintbrush. Gently brush the pesticide around the entrance hole on the bottom of the nest, being careful not to clog it.   Avoid shaking the nest, as it may prompt the wasps to attack. The yellow jackets will collect the pesticide on their bodies as they leave and enter the nest, and then ingest it when they groom themselves. It should take about 5 days for the entire nest to be killed. To protect yourself when approaching wasp nests, dress protectively in a high-necked top with long sleeves, gloves, and a head net, hat, or a headscarf.  Purchase carbaryl online or in hardware stores. At dusk, approach underground yellow jacket nests in your garden. Carefully pour liquid pesticide down the holes. Immediately toss a full shovel of soil on top of the hole to prevent the wasps from emerging.  You can find diazinon in hardware stores as well as online. Avoid harming yellow jackets that cross your path. This causes a pheromone to be released which attracts other wasps, signaling them to attack. Instead, avoid them or sit still as they approach you and wait for them to leave. Fill the reservoir of your wasp traps with a liquid attractant such as sugar water or soda.
