Thread: WASPS it doesn't take them long

I just recently roach bombed a nest in my roof. A few days before(X-Mas Day) I was on the phone and heard a gnawing sound in my roof, I was about to leave for a long drive for X mas but thought I'd check it out incase it was borers. Grabbed some mortien, and torch, and up into the roof I went.
Wasps, but they didn't, look like european, so I pulled back a bat I heard them under. I could hear them in the bat, below me, but I was curious to watch the ones coming in, as they seemed smaller and dark(even though I was sure most native wasps aren't communal), and sure enough, pow right on my thumb, got the hell outta the roof real fast. Great throbbing thumb and four hour drive, anyway, two roach bombs sorted them out.
Years before I had a huge nest in the back lawn, with two massive holes you could fit your fist in, and like you, I casually walked out, poured heaps of peterol in each hole, walked back, got lighter, and went through the frenzied cloud of wasps, and lit them. Didn't realize how much of a risk I was taking. They release a feremone(sp?)when scarred that makes them all swarm and attack, so be careful.

You can bait them easily too.

Mix some mince with a few drops of "Frontline" (spot on liquid, used to treat cats and dogs with fleas).

Sandwich the poisoned mince between a couple of boards, to prevent birds or lizards getting to it, and place it somewhere the wasps frequent.

The wasps take the mince back to the nest and they die.

If you find dead wasps around the bait, it's too strong. So it can take a bit of trial and error to get it right.

Apparently this is the method used by the CSIRO, but won't tell you about, because the "Frontline" is not specified for that particular use.

GNAWING,. I had this sound in the ceiling above the kitchen. Though it was a possum, banged on the ceiling but it didn't stop.
Put a possum trap up there and nothing caught. Then though maybe it's rats. Heard bits of wood being ripped off.
Don't tell me Wasps also gnaw.
That might explain why the bang on the ceiling didn't stop the noise. Wasps wouldn't care.

If you want to petrol bomb a nest, it has to be done in darkness when they are all home in the nest. No good doing it during the day, as some will escape also the danger of you being attacked.

petrol will not get them all, thy just flop around for a few seconds then move on.

use Kero or Diesel and no match.


if thy swarm lay on the ground, dont run

Hmmm, the mud daub wasps around here so far have been really friendly. We both just stay out of each others way.

Seen it happen - I was slashing a scrubby paddock and drove straight over the top of a nest ....Tell ya, Jesus might be able to walk on water, but I can run on air I was off the tractor real quick and luckily I didn't get stung. The little buggers went crazy. I had to wait 'til well after sundown to retrieve the tractor.

Found a spraycan called Waspkill I think.It has a long squirt rather than a spray. Can stand back 10 ft or so and hit the nest. Kills them dead instantly, never seen anything like it before. Bought it from Tom Grady our local Rural Supply.

I have to do something like this to get rid of a couple of large meat ant nests. Have tried the kero (and petrol.....another story), but there's too many holes.
