Stinging Insects

Yellow Jackets

 

Vespula spp.

 

colour: Abdomen usually has yellow and black bands, but some species are white and black, and two northern species have red markings.
Legs: Six
Shape: Triangular when laterally viewed, with bulbous parts.
Size: Yellowjacket adult workers are 3/8-5/8 in (10-16 mm) long, depending on species; queens are 25% longer.
Antennae: Yes
Flight: Yes

 

Habits
A paper-carton nest which eventually has 30-55 compartments surrounded by a paper “envelope”. It is made of chewed cellulose by a queen who has over wintered and is ready to lay her eggs, one in each compartment. Eventually there will be a number of paper-like combs attached one below the other, and covered with many layers of “paper”. Yellow jackets are social insects that live in colonies. Each colony has a queen that lays the eggs, female workers that do not reproduce, and males that come forth in late summer, being reared in the same cells that were earlier used for the workers. Larger cells for rearing queens are built at the end of the season. Mating occurs in fall after newly emerged queens and males leave the nest. Only queens who have mated hibernate and live through the winter. The past season’s queen who built the nest, as well as the workers and the males, all die.

 

Threats
Depending on the species, nests may be built on the ground, or in shrubs, trees, or buildings, such as houses, garages, and sheds. Yellow jackets are beneficial as they eat many pest species, however, they may sting when the nest entrance is approached, and can be aggressive, stinging several times.

 

Prevention
Professional pest control operator should be contacted to seek out the source, treat nesting and remove. Treatment to nest‘s should be performed when adults are surrounding or nearby. Nests quite often can be in wall voids, and other gaps and openings in a structure. Such void areas should be treated and cleaned out to prevent other insects from foraging to feed on dead pests in area.

 

Paper Wasp

 

Polistes spp.

 

colour: Brownish with yellow markings; some species with reddish markings.
Legs: Six
Shape: Triangular when laterally viewed, with bulbous parts.
Size: Paper wasp adults are about 5/8 to 3/4 in (16-20 mm) long. Paper wasps have long legs. The middle tibia has 2 apical spurs.
Antennae: Yes
Flight: Yes

 

Paper wasps get their name because they make paper-like nests with an umbrella-like shape.

 

Habits
There is a single layer of comb with cells that open downward, hanging down by a single, narrow strand. There is no outer “envelope”. The cells remain open. The thin strand may help keep ants and other intruders out. Nests are smaller than 6 by 8 inches, with about 150-250 cells. Paper wasps eat insects and nectar. A paper wasp queen that has over wintered begins to build a nest in the spring. This primary queen nest-builder may be joined by other, secondary, queens in building and maintaining the nest. A single egg is laid in each open cell and the larvae are fed protein from insects. Later the cells are capped when the larvae are ready to pupate.

 

Threats
Nests are hung from almost any protected structure-twigs and branches of trees and shrubs, porch ceilings, window and door frames, soffits and eaves, rafters, deck floor joists, railings. Paper wasps are beneficial insects, though if disturbed, they can and do sting, which can be a problem if a nest is touched by someone or if there is a lot of human activity near a nest.

 

Prevention
Professional pest control operator should be contacted to seek out the source, treat nesting and remove. Caution should be taken when trimming shrubs, picking fruit, etc., by checking for nests and activity that may be hidden.
