Wasps are seasonal insects. They begin their life in early spring when the queen lays her eggs. They peak around summer and the hive dies off by winter except for the queens who hibernate to start the process over again the next year.
The question is whether they will return to the same location is a complicated one. Technically speaking, wasps do not return to the same location every year. This is because they do not reuse old nests. The wasps only use their nests once in a lifetime so if you can wait them out, there is a good chance that your problem is over permanently.
Things are however not always this straightforward. The wasps built the nest in your yard or home because it is an ideal location. A different queen may think the same thing and invade another area close by that is equally as desirable. Although wasps do not occupy empty nests, they may recycle the material from the old nest to build a new one close by.
If you notice wasps coming back to your property every season, it means that your yard or home is ideal for nesting. It might be that your roof is exposed to the sun throughout the day (wasps like warm nesting sites) or there are gaps and services that let the insects in. There might also be an abundance of nest building material such as garden sheds, trees and fence panels. Finally, it might be that there is an abundance of food and water on your property.
What to Do With Wasp Nest
You don’t necessarily need to remove the wasp nest after the hive has died off in late autumn/winter. If you have never had a wasp problem before, there is a high likely hood that they won’t return after this season. Again, wasps typically do not reuse their nests while others won’t occupy an empty nest. The nest will simply crumble naturally into dust after a while, usually years.
It is also a good idea to leave the nest intact if it has been treated with chemicals to kill off the insects. One reason is worker wasps might get trapped overnight while foraging and don’t make it to the treated hive. Leaving it intact increases the chance of killing the entire colony.
Chances are also good that the present location of the nest is ideal so another queen might build her nest in the same location next season if the spot is empty. Since wasps don’t reuse the nest, the old hive prevents a new one from popping up in the same location.
Lastly, it is not uncommon for wasps to forage in empty or old nests. The treated nest intact means that wasps from other hives can carry the treatment back to their nest and contaminate it. Professional-grade insecticides last a long time.
Hire an Expert to Getting Rid of Wasps
Wasps are vicious especially if disturbed. You can almost guarantee getting stung if you attempt to treat or destroy a wasp nest on your own. Most over the counter treatments simply don’t work. Pesticide and chemical control regulations and laws limit the potency of active ingredients that you can buy over the counter.
Other times it may not be necessary to remove the wasps but rather wait them out. Mud daubers, for example, are naturally docile and rarely sting. They help with pollination and also eat common nuisance pests including spiders.
