The only insects I have a kill on sight order for are fire ants. I am pleased to report that I was successful "nagging" the fire ant colony with a shovel to leave my compost pile without using poison that would hurt beneficial flora and fauna.
I haven't been stung or bit in over a week. 
I hear that! Here in southern Tas, we have ants called 'jumping jacks' .... *bad ants*
They are large, agressive ants with a horrible sting ... not a bite, but a really bad sting .. you know the kind, causing ulcers and other necro BS of surrounding tissue ... some kind of nasty toxcin
https://en.wikipedia.org/wiki/Jack_jumper_antThey like to jump off the ground, onto and up the legs, stinging repeatedly ... sigh.
*Luckily* I haven't come across, but they are in this region .. Tas has more venomous, agressive nasties .. of all kinds .. imaginable. Don't start me on *snakes*.
It's a who's who .. or a plethora ... of the most toxic, aggressive and *common* creatures available, down here!
...
I do get another 'wasp-bee-ant' related critter .. it's harmless to hoomans and very pretty ... a 'differently' evolved wasp - no sting to speak off and *no wings*, so it looks like an ant ... a *big*, irridescant ant .. but it's not, it's a flightless wasp!
