Hornets nests resemble a large, inverted tear-drop shaped ball which typically is attached to a tree, bush or side of a building.
Hornet nests may contain thousands of wasps which are extremely aggressive when disturbed.
Insect Hornets are most commonly are found in hollow trees. However, hornets nests also can be found in barns, attics, hollow walls, and abandoned bee hives.
The hornets nests built in unprotected places are covered with a brown envelope (paper) composed of chewed plant fibers. The brown color will help distinguish it from the more common gray nests of aerial nesting yellow jackets (also called baldfaced or black hornets).
Paper wasps, hornets and yellow jackets construct nests of a paper-like material which is a mixture of finely chewed wood fragments and salivary secretions of the wasps.
Paper wasps typically build their umbrella-shaped nests under eaves and ledges.
These wasps are not as aggressive as yellow jackets or hornets, and can be eliminated rather easily with a wasp and hornet spray such as PT Wasp and Hornet Killer.
Hornets-
These have large grayish-brown carton like structure, many
times hanging from a tree or bush. They are considered wasps.
Control:
Treating hornets
should be done at night, without shaking the nest.
You will need a quick spray of PT Wasp and Hornet Killer
Care should be taken when spraying directly
on trees and bushes with product, spraying as little as possible.
If you spray
on a house, it is recommended that you clean the area the next day.
When dealing with social wasps, wear protective equipment including a
bee hat, long-sleeved shirt, coveralls, eye wear and gloves.
Locate the wasp nest by
examining all protected areas in the vicinity of wasp activity.
Simply removing
the wasp nest will not resolve the problem, because surviving wasps will reconstruct
a new one.
The best
strategy is to treat the wasp nest at night when all the workers and queen are
present.
Spraying into hornets nests should ALWAYS be done at night.
They are far less aggressive and are all at home.
This tactic maximizes the effect of the pesticide application by
killing most if not all of the wasps.
If treatment is made at night, avoid
shining a light directly on the nest or use a red filter on the flashlight.
Daytime treatments are successful when the wasp nest is treated or if the wasps
present on the nest are killed.
Then, the wasp nest is removed and the attachment
area treated.
Returning workers looking for the wasp nest contact the residual and
die.
Complete the job by removing the wasp nest, particularly if it is inside an
attic, wall void, etc. This service prevents secondary infestations by
dermestids or other pests.
For these hornets we recommend a Wasp and Hornet Killer, spraying into their
wasp nest to get a quick knock down then an insecticidal dust like Delta
Dust to dust into the their entrance at night....wear protective clothing
and try not to use any lights...even at that you still can get stung.
Treatment can be accomplished by applying a wasp freeze-type , PT
Wasp and Hornet Killer directly into the nest opening.
Hornets nests have a single opening, usually toward the bottom, where the wasps enter and exit.
It is essential that the paper envelope of the nest not be broken open during treatment or the irritated wasps will scatter in all directions, causing even greater problems.
Hornets are far more difficult and dangerous to control than paper wasps.
A full wasp suit sealed at the wrists, ankles and collar is recommended when disposing of a hornet nest.
Treatment of wasps, hornets, and yellow jackets is best performed at night;
paper wasps can be eliminated during the daytime provided you do not stand directly below the nest during treatment.
Most wasp and hornet sprays cause insects to drop instantly when contacted by the insecticide.
Standing directly below a nest increases one's risk of being stung.
