hundreds of thousands
If there is a nest that is abandoned you should destroy it.
Yes, yellow jackets typically do not return to the same nest every year. They build new nests each spring and abandon them in the fall.
Yellow jackets cannot rebuild a nest without a queen. The queen is essential for laying eggs and establishing a new colony. If the queen dies or is removed, the existing workers may continue to care for the nest for a short time, but they will eventually die off, and the nest will not survive. Without a queen, there is no new generation of yellow jackets to continue the colony.
Yellow jackets have several enemies that will eat them. Bears will root out a yellow jacket nest , as will raccoons, skunks, and badgers. Additionally, certain birds will eat lone yellow jackets as well.
In the ground, walls, attics, and tree stumps.
Hornets don't normally nest in the ground. Yellow Jackets nest in the ground. You can kill them by pouring gasoline in the hole and running.
Well, no, once yellow jackets die they don't really go anywhere. I guess if they died in their nest then they would stay there (or more likely booted out the door by other wasps that didn't want a corpse hanging around)what time of year do they hibernate?
Yellow jackets can build an in-ground nest relatively quickly, often within a few weeks. Typically, the initial phase of nest construction occurs in the spring when a fertilized queen establishes the colony. By late summer, the nest can grow to house thousands of wasps, depending on environmental conditions and food availability. Overall, the entire process from establishment to peak population can take just a couple of months.
Yellow Jackets: Yellow jackets are small (half-inch long) wasps marked with yellow. Colonies are initiated by overwintering queens that make paper nests underground, but occasionally in hollow trees, wall voids and attics or on a branch over a stream. A fully developed nest may contain from a few hundred to many thousand adults. Yellow jackets feed on a variety of pest insects, but will also forage for meat or soft drinks at picnic, camp and garbage sites. This habit often brings them into close association with people. Good sanitation in picnic areas can help reduce problems with these pests. Solitary scavenging yellow jackets are usually non-aggressive unless handled, but become very aggressive as a group if they believe their nest is threatened. Yellow jackets will vigorously pursue an intruder who threatens their nest and are generally considered the most dangerous of the social insects. I cant post the picture for you, but yeah these little guys chased me tonight when i was mowing my yard and one got me....little sucker.
Don't try to do this yourself. Contact a qualified exterminator. Your local government or Yellow Pages should be able to direct you to one or more.
To get rid of yellow jackets inside your wall and crawl space, you can try using a commercial insecticide specifically designed for wasps and hornets. Seal off any entry points they may be using to get inside. If the infestation is severe, consider calling a professional pest control service for assistance in safely removing the yellow jackets.
Skunks are the most likely animal to dig up and eat a yellow jacket's nest, even if it's 3 feet off of the ground on the underside of a deck. Raccoons have also been known to eat the larvae out of yellow jackets' nests.
