And jumped 4 foot in the air to avoid my bricks
Bricks you pegged at them or a structure they leapt over?
Bricks I was throwing MF, despite being a decent size target I usually didn't get close. The one time I did, the thing jumped vertically 4ft in the air when the flying brick was basically about to be on top of it.
Ironbark, there is still an orchard (well whats left of it, the old guy must be 90 now and the family does not look after the trees much) with old sheds and crap about 40 metres away. thats where I reckon most issues come from. Only thing worse would be chickens as you say.
When we had runs of 40 degree days, about 500 cockroaches came out of the verge inspection pit for the road drain. I drove out at night and saw the ground moving under the headlights. Turned the car off, went and mixed some permethrin (fast knockdown) and sprayed around the inspection pit. Then followed up with bifenthrin (long lasting) an hour later. The next day the verge was covered thick with dead cockroaches, followed the line down the fenceline and into next doors.
