These pyrethroids are present in over 2,000 pesticides today. While these chemicals all have different names, they work pretty much the same way. Once a wasp ingests one of these, it slowly breaks down its nervous system. This quickly leads to paralysis.
Bleach will kill almost any living organism, including wasps, but it is not an effective way to deter them. PMP doesn't advocate the use of bleach as a form of pest control, as it can irritate the skin and eyes of anyone who comes into contact with it.

In short, hornet nests are often much larger, set up mostly in tree branches or leaves, and have a paper-mache appearance. Wasp nests are smaller to keep their smaller colonies safe, have distinct hexagonal openings, and can be set up in nearly any sheltered space.
Wasp control is best done in the spring when queens are building new nests.
With brains less than a millionth the size of humans', paper wasps hardly seem like mental giants. But new research shows that these insects can remember individuals for at least a week, even after meeting and interacting with many other wasps in the meantime.
Spray until nest is thoroughly saturated to kill the entire nest population. Exit area immediately and remain outside the treated area until all sprays have dried. Wait at least 24 hours before removing the nest.
