Using a bombardier beetle parts using the acid glad and parts. Why bec the beetle shoots acid at u why not make a weapon like a hand held acid cannon maybe sling shot or an acid cannon on base. Plus stink bug make stink bug bombs maybe a sling shot bomb as well. Just ideas 

I want to see real traps made. Knots, snares, the works. Home alone style madness.

That would be awesome. But also like old school castle stuff like big arrows and catapults.. bad thing I'd they need to make bugs actually attack your base. But also weapons need to be more upgraded and armour different bug parts and so on.
