I think insects have little holes all over their bodies, in which air gets inside by itself through some physics shenanigans. It doesn’t need to be actively sucked in like with lungs, it just happens because they’re so small.
This method doesn’t scale up though since if you’re bigger, you need more air, and having little holes all over your body won’t cut it. Thats when you know you need lungs, and that’s why you don’t see insects the size of a dog these days (thankfully).
There used to be times in the Earth’s history (Carboniferous) where the air’s composition was different though, and since it had more oxygen in it, insects could grow a lot larger.
No because you’re likely too big (no offense) :(
