Nests are designed by queens and built by workers in early spring, and the colonies grow throughout the late spring and early summer until reaching peak size somewhere around August. The end of summer also finds wasps at their most aggressive and protective, making it a dangerous time to try to get rid of them.  Early in the year, the nests are smaller and more manageable. Get in the habit of patrolling the area around your home for wasp nests in the early season, before they've grown to dangerous sizes. If you kill the queen, there will also be no risk of the nest being rebuilt that year. If it's late in the season, it's probably best to wait it out and let the frost kill off the pests in the next 30-60 days. Then, you can knock the empty nests down to ensure that they won't be repopulated next year. Anytime you go hunting around for wasps, you need to keep yourself well protected. You probably don't need a full-on chemical protection suit, but taking a few steps in precaution can keep you from coming home with nasty stings if you get swarmed.  You need to wear thick, long sleeves and pants, heavy gloves, a hood that covers as much of your face as possible, and eye protection. Even if it's super hot outside, don't skimp on the layers and the thickness of the clothing. If you get swarmed by wasps, it's important to not over-think it: run as quickly as possible away from the wasps. While some people report that swinging articles of clothing or turning abrupt corners can be effective at shaking a swarm, the best way to get away is to run as fast as possible and get inside. If you're having a consistent problem with wasps in your area, it can be quite frustrating. But don't keep swatting them one at a time. Get rid of them at the source and get them away from your home. Find the nest and kill the nest and your problem will solve itself. Yellow-jacket nests are quite small, while wasp nests will be somewhat larger and more bulbous, like a papery football.  Wasps tend to build their nests in loose piles of wood,...
