I have a long history of fairly extreme chemical warfare on insects, particularly blood-sucking kinds that want to leave a person with malaria, and much else.
In Botswana, I had this nightly ritual to clear the
rondawel of mosquitos. I would ensure all the mosquito screens were closed. Sleep under a net, etc. I hated the green slow-burn pyrethrum incense spirals. The mozzies seemed to fly on unharmed, regardless I hit them with direct blast from the spray can. Then one day I grabbed a can, blasted it, and the insect started to lose altitude immediately, crashing to a stop. I looked at the can, and it was collar spray starch! About 10,000x as effective as anything else one could buy! From that point on, I got way more aggressive with what I would take on insects with.
You can't go anywhere in that bush without collecting ticks, though I managed not to let any get to my skin. Getting them out of the clothes was easiest done with a drop of 105 Octane Aviation AVGas.
Tsetse flies were harder to lose. Painful, and they cause trypanosomiasis (sleeping sickness). The list goes on. My ultimate deterrents were extreme solvent hydrocarbons, poisoned vaseline, boiling water (on larvae), and fire!
[Edit: I forgot Bayer 70 to take out the little snails on water hyacinth near the shores of dams I would sail on. These would propagate bilharzia. Bloody fluke worms that get in your blood! ]
