Us and Them

I've squished a lot of bugs in my time. Ants, especially as of late. It must be really tough to be an insect what with all these people around. We squish them. We run over them. We suck them up with our vacuums. We rinse them in scalding hot water and send them down the drain (Calm down. I only use scalding hot if it's a big one and I feel the need to stun it first for my own safety. Other wise, a comfy tepid temperature will do.) We unleash various forms of chemical warfare on them (Lysol seems to be a good cheap insecticide. For me anyway. And cinnamon. Ants really don't like cinnamon. Plus, it's such a fine dust that it clogs their networks of tracheas that they breathe through and they asphyxiate. Take that nugget with you when you audition for Jeopardy!. You'll be a shoe-in. But I digress....).
We also unwittingly house them and feed them. Sometimes, they feed on us (mosquitoes,ticks and such). And ya know, they were on this planet first. We must seem like parasites to them. If you follow that line of reasoning, we live off their land; some of us eat them. We can die from infestations and bites. They can kill us. We have a sort of reciprocal host/parasite relationship with them. This goes for most species on the planet really. That's another post altogether, though.
My point is....as our population increases and each one of us kills more and more insects, do they adapt by breeding more and more? Do their populations grow with ours? Insects outnumber us, I think. But just to stay ahead of us, do they breed more if we do? I just wonder if there's been a study on this. That's all.
