Wasps are a diverse group of insects. In Australia alone there
are over 12,000 species, ranging from the tiny diapriid wasps,
which are barely visible to the naked eye, to the spider and
cicada-killer wasps, capable of taking large prey. Most wasps have
carnivorous larvae that feed on other insects and spiders. The
adults provide food for them by capturing prey or by laying the egg
on or near the food source, which might be an egg, larva or pupa of
another insect.
Wasp control is essential when they have large populations near
your living areas.
Why are they a pest? If you invade their space they will attack
you and sting repeatedly, unlike bees which can only sting
once.
The Papernest wasp’s nest, is usually small (about the diameter
of a 50c coin), fully or partially exposed, honeycombed in
appearance and is often found on the underside of eaves or hanging
off a branch.
