Spring in Australia and the wasp queens are out and about. If you don’t kill them now there will be hundreds of these introduced pests everywhere come summer to spoil your barbecue or sting your kids. Last year I managed to tread on a European wasp’s nest and was bitten dozens of times. Let me tell you it was not pleasant, and the swelling and irritation from the bites lasted for many days. People who are allergic could easily be killed, likewise pets.
Simple milk bottle trap.
You can easily kill them with simple milk bottle traps. You can use the recipe below (but you will kill some other insects too, such as bees. A poisoned meat bait is better as it will only kill wasps and the occasional blow-fly (if the wasps allow it near the rotting meat. You can easily make a poisoned meat bait from mince and a readily available spot-on (dog) flea chemical. If only one household per suburban block did this we would eradicate the wasp from our cities.
The Kiwis are wiping out European wasps. Let’s do it too. Lobby your pollie: https://www.stuff.co.nz/environment/wasp-wipeout/87865462/the-weapon-to-wipe-out-wasps-the-story-of-vespex–wasp-wipeout?rm=m
‘For those who would like queen lure here it is again:Use a 1.25 L soft drink bottle with 3, 10mm holes, approx. 150mm from bottom of bottle. Make up a solution 8 tablespoons of honey in hot water with a 2 teaspoons pure vanilla essence Queen red label 35% alcohol this will do 4-5 traps, divide bait between traps, top up with water to just below holes replace cap and hang in a sunny spot in garden, near water. Fruit trees with curly leaf is a good place, bait will take a week or so to activate. Shake every few days to let bait dribble out .keep in place until January. Strain out when full, reuse and top up bait with water. Replace bait every 4-5 weeks Will also catch workers Jan-April plus flies.’ European Wasp Control Project Facebook Group: https://www.facebook.com/groups/927515897312332/
Left European Wasp; Right native Paper Wasp.
I bought one 2.68ml pipette of Frontline (large dog) from my local Safeway store for A$17 (April 2018). Diluted 100 times (268 mls) with water this was (or will be) enough to prepare 52 x 20 gram minced meat baits (I bought 24 x 20 grams meatballs from Safeway for $6) which I simply slipped into a used plastic milk bottle I had drilled a few 12mm holes in and hung in the garden after training the wasps for a couple of days with unbaited mince. That single purchase should kill very wasp within 200 metres of our property for several years!
NB: European wasps are introduced pests in Australia and New Zealand. The meat baits carefully protected like this will not in my experience kill any native creatures. (Blow Flies are also an introduced pest – at least the sheep one is!).
