...Fire Ants. That's something.
I don't know why you people who live in bug-infested areas don't just buy a drum of Malathion, and use it full strength. Fuck the EPA. I worked at this place where, at lunch, after eating, we'd amuse ourselves by dipping a long dried weed into the pure Malathion (undiluted) and go up to these big-ass spiders, and I mean big as in fucking enormous, and as you approached them slowly, you'd get about a foot or so away, and suddenly, they just plain up and died. Without a twitch. It was like you hit them with a blowtorch.
I tried to always keep the breeze at my back when using that stuff. Deadly.
I'd let these little bastards finish eating all the fire ants, then I'd nuke em. And I'm wondering why you couldn't make some sort of electrified door and window frame, that pulsed like an electric fence, and would keep crawling insects out of your house. Just zap the shit out of any crawly thing, and turns off when you open the door, and back on when you close it. And turn all of your screens into bug zappers.
Speaking of, I used to put apples and carrots on the wire of our electric fence, where I used to live, on this ranch. The deer would come along an go 'Hey! Apple!' and commence to filching it. Then ZAP! Boy, those fuckers can jump high when properly motivated.
And they never learned.
