The bugs are obviously intensely territorial.

Why?

If they scurried away, we wouldn't have to shoot them. It's not like we want to eat them.

They're in an arms race with an equally fierce species that we haven't seen, like ants vs. thermites.

...I can think of at least one fierce and already known species that are invading their territory...usually carrying large guns...
