Pest Control for Wasps
Pest Control for Wasps
Paper wasps and hornets may become a nuisance when nesting around homes and other structures where people live, work or play. It is their painful sting that causes alarm and fear. The same nest is usually not reused the following year, the only exception to this rule is the paper wasp, who may occasionally return to last year’s nest.
Paper Wasp and Nest
There are two kinds of Australian Native Paper Wasps and both are quite common in Australia. The wasps that build rather long narrow nests mainly hanging in trees or shrubs are Rhpalidia paper wasps.
The second kind are called Polistes and they make a nest in the shape of an upside down wine glass, that looks like the holey side of a crumpet.
Female paper wasps scrape the wood off dead sticks to create the paper for their nest, making them one of the earliest papermakers in history.
Their sting is characterised by localised intense pain and swelling, for people who have developed an allergy the sting can be life threatening.
European Wasp Nest
The European Wasp Nest is also made from the papier mache material, however all of the chambers are internal and covered. You may find these nests to be located underground or in a crack or crevice, really anywhere they have access to shelter.
The secret to finding the nest is knowing that European Wasps travel in a straight line to and from a food and / or water source. You can establish the location of the nest by providing a food or water source and following the wasp back to the nest. Sounds easier than it actually is. European Wasp Nests will have wasps streaming from the nest at the intersecting flight path. Be careful not to get bitten. Mark the nest location and call a professional to treat.
The European Wasp was accidentally introduced into Australia from Europe. The European wasp has a very painful sting and will swarm out of the nest if feeling threatened, unlike bees they can sting many times, a sting on the neck can cause swelling leading to death.
The European Wasp can be easily differentiated by the black spots on the yellow abdomen in between the black bands.
Mud Dauber Wasp
Mud Dauber Wasps vary in colour but are often all black with orange or yellow bands and markings. They build their bests from mud or clay. Mud Dauber Wasps are not aggressive and rarely sting.
They are solitary insects, nests are constructed by the female and are attached to rock faces, tree trunks, inside cavities such as holes inside tree trunks or machinery and on buildings.
Their nests are unsightly and can be knocked down with ease, preferably when the owner of the nest is not around. Treatment does stop them from returning to their mud nest and stops the progression of the larvae turning into an adult.
The Hornet is the largest of the wasp family and is solitary, it likes to catch caterpillars and spiders to lay eggs in to feed its young.
The hornet will not usually attack unless provoked and in a position where it feels vulnerable or threatened.
