I really don’t like gardening advice that divides the natural world into lists of good and bad bugs. From nature’s perspective all creatures have a role, even the much despised paper wasp.
Paper Wasp Biology 101
Wasps perform important duties: some wasps eat other insects, other wasps are scavengers, acting as nature’s garbage disposers. That’s not to say that wasps don’t earn some of their bad reputation. I’ve found that, unlike honey bees, they can sting without much warning. And their sting is sharper, reminiscent of the unpleasant after-burn of cheap booze.
The wasps I see the most around our house are paper wasps (family Vespidae and probably of the genus Polistes, though there are many different kinds of paper wasps). Paper wasps like to build their small nests under the eaves of the house. Their diet consists of caterpillars, flies and beetles—anything that eats those kinds of bugs are a friend of mine. Nests consist of around 30 to 40 wasps–workers, queens and drones. They are much less aggressive than hornets and yellowjackets.
How I stopped worrying and learned to love the paper wasp
Of course, sometimes paper wasps build nests where we don’t want them. A neighbor was having her house painted a few years ago and called me over to remove a nest of paper wasps. I put on my beekeeping suit and pulled the nest off the eave of the house only to discover that you can’t move paper wasps. They just flew back immediately to where their nest had been.
Wasps don’t like scented products such as perfume, cologne, aftershave or hairspray. Come to think of it, if I were a wasp I’d sting people over this stinky stuff, particularly at the gym. But I digress.
I suppose there are legitimate reasons to kill the occasional nest, but I wish more people knew the important role wasps play in our gardens.
And we really need teach everyone to tell the difference between wasps, honeybees, yellowjackets, hornets and bumblebees. You wouldn’t confuse an iPhone with and Android.
Fortunately, UC Davis has a video:
