Australian Paper Wasps in the Garden – another case of Knowledge is Power!

Often, when I talk to people about wasps, I find they look upon them very unfavourably as a menace to family health and often for this reason… something to be destroyed on sight.

Most often the wasps that come to these people’s minds first are in the Paper Wasp family which, as their name suggests, build their fantastic nests out of papery material often found in protected locations under eaves and hidden in dense vegetation like hedging. I believe one of the reasons they are more frequently found close to dwellings in suburbia is that they havn’t got as much access to all of the nice high ‘out of our way’ spots that taller trees and natural dense stands of vegetation that they’re used to in the wild. Lawns make terrible wasp habitat!

The thing is most native Paper Wasps have very little interest in attacking you unless they regard their nest is under threat. Fairly understandable really… living in a colony means that many of their young’uns are together and under threat at the same time, hence the desire to defend said colony is relatively strong. Human parents would probably get pretty violent if they found their Childcare centre was under attack too!!! ;-p

The only time i’ve been attacked is if I’ve accidentally pruned too close to a nest I neglected to detect, in which case I say ‘fair enough guys, message received!’. Working close to active nests, i’ve found remaining calm also helps in keeping the wasps calm. Of coarse I keep an eye on them for warning signs too, such as individuals on the nest beginning to turn and face you.

Now, don’t get me wrong… if a member of your family is allergic to wasp stings I can fully understand the need to keep paper wasp nests away from your living areas etc.

BUT… I happily co-exist with these guys both where I live, and in gardens I work at all around the Central Coast and Hunter Valley. Not only that, but they provide a POWERFUL pest control function in these gardens which saves me a lot of effort and energy.

As soon as a population establishes itself within range of a vegetable garden I see almost no Cabbage Patch Butterfly caterpillars on Brassicas (Cabbage, Cauliflower, Kale, Asian Greens, Broccoli etc.) with wasp individuals continually scouring leaves for more grubs.

Native Paper wasps are also the only thing i’ve seen actively attempting to control the larvae of 3-Striped Potato Beetle (Lema daturaphila) making me think they’re likely to go for larva of Leaf-eating Ladybeetles (Epilachna spp.) too. Natural Pest Control Champions!

So next time you find a Native Paper Wasp nest, take a deep breath, think again and evaluate all of the positives and negatives of its presence and location. If you still want it gone, perhaps think about armouring up and translocating the nest rather than burning or poisoning the whole colony.

A bit of knowledge can make all the difference in how you regard these amazing little critters!

One thought on “Australian Paper Wasps in the Garden – another case of Knowledge is Power!

  1. I had a nest about 30cm from the tap on the base of my water tank, they never attacked me using the tap. One day they moved out though.

    I remember hearing someone at the bee club say that a lot of people claim to be allergic to bees after being stung and getting a welt near the sting not knowing that this is the normal reaction to getting stung. Conversely, Macaulay Culkin died from a bee sting.
