Spring Is Here and So Are Stinging Pests.
Paper wasps, hornets and yellow jackets are potential health threats to Omaha, Bellevue, Nebraska and the rest of the Midwest. Hundreds, (perhaps thousands) of people in the United States die each year from wasp control allergic reactions in Omaha to the venom of these insects.
Wasps, hornets and yellow jackets are more dangerous than honey bees and should be treated with respect; nests should be eliminated with great care and in a specific manner. Omaha Pest Control has over 30 years of experience dealing with the stinging pests listed below.
Paper wasps, hornets and yellow jackets construct nests of a paper-like material which is a mixture of finely chewed fragments and secretions of the wasps. Paper wasps typically build their umbrella-shaped nests under eaves and ledges. These wasps are not as aggressive as yellowjackets or hornets, and can be eliminated rather easily with a wasp and hornet spray sold at most grocery and hardware stores. These formulations have an added advantage in that they often spray as far as 20 feet.
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. Following treatment, wait a day to ensure that the colony is destroyed, then scrape or knock down the nest. This will prevent secondary problems from carpet beetles, ants and other scavenging insects.
Hornets are far more difficult and dangerous to control than paper wasps. The 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. The nests are often located out of reach and removal is best accomplished by a professional pest control company.
Extermination and treatment can be accomplished by applying a wasp freeze, aerosol insecticide or dust formulation directly into the nest opening. Hornet 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. Following treatment, wait at least a day before removing the nest to ensure that all of the wasps are killed.
If hornets continue to be observed, the application may need to be repeated. Experienced pest control operators will sometimes remove a hornet nest which is attached to a branch by slipping a plastic garbage bag over the intact nest and clipping it at the point of attachment.
Yellow jackets are another dangerous wasp encountered around homes and buildings. Nests are often located underground in an old rodent burrow, beneath a landscape timber, or in a rock wall or wall of a building. If the nest can be located, it can usually be eliminated by carefully applying a wasp spray insecticide into the nest opening.
Sevin ™, or Ficam ™, dust is also very effective provided a hand duster or similar type applicator is used to dispense several puffs of the insecticide dust in to the nest opening.
Approach the nest slowly and do not shine the beam of the flashlight directly into the nest entrance as this may startle the wasps; instead, cast the beam to the side to illuminate the nest indirectly and place the light on the ground rather than in your hand.
Similar to hornets, yellow jackets are extremely aggressive when the nest is disturbed. It may be prudent to call a professional Omaha pest control company, particularly when access to the nest is difficult. If the nest is located away from high traffic areas, another option is to wait and do nothing. In Nebraska, wasp, hornet and yellow jacket colonies die off naturally after the weather turns cold, and the paper carton disintegrates over the winter months.
