Other less civilized tropical countries still use DDT regularly, to great effect.
Maybe they have something there.

Around here, skeeters are few and far between thankfully.
But ticks, we got ‘em. And they like me a little too much.

Last couple of years, I’ve been using a soap loaded with lemon-eucalyptus oil that my wife makes.
It’s seemed to help quite a bit, at least for the flies and skeeters.

I keep a fair number of bug bombs in storage, and a fair amount of DEET (100%) liquid on hand, as you can guess, bugs are a pet peeve of mine.
