Yellowjackets, paper wasps and hornets sting can be a potential
health threat to people who are allergic to the venom. Persons
who develop difficulty breathing or swallowing, wheezing or
similar symptoms of venom allergic reaction should seek medical
attention as soon as possible. Itching, pain and localized
swelling can be reduced with antihistamines and a cold/ice
compress. Honey bees have a barbed stinger. Only the honey
bee leaves her stinger in the skin. Yellowjackets, paper wasp and hornets have a lance-like stinger without barbs and can
sting repeatedly. Please contact us to get rid of wasps in
a professional way.
Yellowjackets
These wasps tend to be medium sized and black with jagged
bands of bright  yellow or white on the abdomen, and have a
very short, narrow waist. Colonies, which are begun each early
or late spring by a single reproductive female, can reach
populations of between 1000 and 10,000 individuals, depending
on the species. The wasps build a nest of paper made from
fibers scraped from wood mixed with saliva. Immature yellowjackets are white, grublike that become white pupae. The pupae emerge
adult and change coloring just before they emerge as adult
wasps. Immatures satges are not normally seen unless the nest
is torn open or a sudden loss of adult caretakers leads to
an exodus of starving larvae.
Yellow jackets are unpredictable and sting if their nest is disturbed. In late summers and fall, their colonies are about to mature and large number of workers go out in search of food for their developing queens. Their main source of nutrition is sweets, e.g. Fruits, ice cream, bear and soft drinks.
Sanitation:
To reduce the threat of yellow jackets minimize use of attractive food sources. People eating outdoors should keep their food and beverages covered until ready to be eaten. Clean up spills and leftovers. Commercial establishments like ice cream parlors, outdoor cafes should keep their place clean. Any spills and leftovers should be cleaned quickly. Keep trash cans away from serving tables, doors and other high traffic areas. By maintaining high levels of sanitation, yellow jackets will never turn up to attractive food sources. Apples, pears and other decomposing fruits falling from trees should be raked up or buried.
Repellants:
A dilute solution of ammonia and water sprayed in and around trash cans and sponged onto outdoor tables and food preparation surfaces can repel yellow jackets from these areas. Use household ammonia, not Clorox (bleach)
Paper Wasps
Paper wasps tend to be golden brown, or darker, with large
patches of yellow or red.  Preferring to live in or near orchards
or vineyards, they like to hang their paper nests in protected
places, such as under eaves, in attics, or under tree branches.
Each nest hangs like an open umbrella from a pedicel (stalk)
and has open cells that can be seen from beneath the nest.
White, legless, grublike larvae sometimes can be seen from
below. Paper wasp nests rarely exceed the size of an outstretched
hand and populations vary between 10 to 100 wasps. Paper wasps species are relatively unaggressive, but they can be a problem
when they nest over entrance door.
Paper wasps create paper nests with saliva and plant fibers. They are beneficial because they eat pests that harm agricultural crops. Paper wasp colonies are divided onto three castes: queens, workers and males. It can sting multiple times. They can build their nests on almost any structure like trees, rocks, wood, playground equipment and buildings. Remove these wasp nets in early spring to prevent large nesting colonies in the summer. Nest removal is dangerous because social wasps can get aggressive when disturbed, especially when their nest is threatened. You can call up avonpestcontrol to remove paper wasps. They will do your work easily.
Bald faced hornet
A single, over wintering queen begins building the nest in
the spring.  Queen lays eggs and tends the first batch of larvae
that develop into workers. These workers tend new larvae and
expand the nest throughout the summer. A mature colony can
have several hundred workers by the end of the summer. In
fall, workers die and next year's queens find over wintering
sites. Baldfaced hornets are generally more docile. But they
can become aggressive and will sting when their nest is disturbed
or threatened. A baldfaced wasp nest is usually constructed
high in a tree. A mature nest is bigger than a basketball,
but pear-shaped, with the larger end at the top and an entrance
hole near the bottom.
Mud Daubers
Mud daubers are black and yellow, thread-waisted, also called
solitary wasps. They build a hard mud nest, usually on ceilings
and walls, attended by a single female wasp. They are not
social wasps but may be confused with them. They do not defend
their nests and rarely sting.
