Paper wasps are considered to be semi-social insects.
They are named for the familiar nests they construct that hang from the eaves of houses and other structures, and sometimes indoors as well. They are about 3/4 to an inch long in length, brownish in color and sometimes a splash of color on the head, folding their wings alongside their body when they are at rest.
The paper wasp is actually considered harmless, and beneficial.
Besides feeding on plant material, one of the items on their menu are aphids, those tiny enemies of everyone’s garden. Also, paper wasps are not very territorial, so not very aggressive. But they are wasps, which means they are capable of stinging, repeatedly, and if their nest is too close to where a lot of people come and go, then careful steps need to be taken to redefine the line between Homeo sapiens and Insectivora. [sniplet AdSense Skyscraper] For openers, Wasps are capable of stinging, repeatedly, and although paper wasps are not considered aggressive, a word to the wise is, always expect the unexpected. Also, there is always outside chance you might have an allergic reaction to the venom. This is not only serious; it can be life threatening. It calls for immediate medical attention and definitely a factor to keep in mind.
There is actually a Wasp and Hornet Eliminator Kit on the market that claims to have all that one needs to do away with a wasp’s nest: two cans of spray insecticide, one pound of insecticide dust, and “duster” applicator. Careful with the dust. It has to be matched up with each particular job or it may not be effective, and possibly harmful. The citric acid in a spray bottle is effective but you have to get fairly close to the nest, and it contains an ingredient that is possibly harmful to mammals, which means us, and the dog and cat.
The best way to go if you brave it alone is to use a power sprayer or a can of wasp/hornet insecticide that has about a twenty-foot range on it. BUT, you have to do it at night when the wasps are inactive (have a flashlight, just in case), and the night raid may have to be repeated. Wear a medical mask just as a precaution against the chemicals, and more than a single layer of clothing.
If it falls within your budget, this seems like one of those, “let the pros do it.” If you aren’t in a position to hire a professional, do your homework, read the labels, and use common sense.
