Social wasps are predators not shed demolishers! video

All social wasps feed their young by chewing up soft bodied insects. I watched in amazement one day as such a wasp, decapitated then de-winged a horsefly and flew off with it!  Now horseflies hurt when they bite…..and mosquito bites can be painful afterwards. Wasps, predate them and caterpillars that eat your flowers or veg!

I have seen the same behaviour many times. Many years ago, as a cub (!) I was camping and decided to make a jam butty! (scouse for jam sandwich!!). Some jam fell onto the outdoor wooden table I was using. I watched as a green bottle landed next to the jam and started feeding on it. I saw the wasp fly overhead and then it landed near the jam. I immediately thought it too would feast upon the jam. It did n’t! It jumped onto the back of the green bottle, decapitated, then de-winged it, chewed through the thorax and abdomen, chewed one part of it and fly off, with that part in its jaws! It left the rest on the table. It was n’t long, as I tucked into another jam butty, that a wasp returned for the remaining half of the fly and carted that off too! Probably the same wasp.

Patrolling flowers

If you watch a wasp from spring to summer, they do patrol flower heads looking for prey items to capture for larval food. Unfortunately this does include honey bees.

Teach children when young!

I have had several wasp nests in my wildlife garden. By taking the time to show my children where the nests had been made and from a distance, watch their flight paths, then pointed out that the wasps were too busy to bother them if they they kept away from the nests and flight paths. At picnics they were taught to remain calm and not to panic, which they never did. Much to the amazement of many panicking arm waving adults! They were never stung!

Will the queen wasp demolish my shed as she chews her way through it?

No she wont! She was just scrapping the outer surface. This large wasp, probably a queen Vespula vulgaris, will use the wood pulp from my shed to make her pulp nest, which will house many other wasp predators! I have watched them chew old, dry cow parsley stems amongst other similar stems. Since the shed was painted, even though it was an environmental friendly paint, I have not seen any wasps chewing the wood anymore.

Beside being insect predators, they also scavenge on dead birds and mammals.

A great article about the benefits of some wasps!
