They certainly do make a heavier use of instincts, but don't underestimate instincts either - some are quite complex and involve many variables. But yes, most of what you see seems to be instinct driven.
This can be demonstrated by introducing small changes that the insect wouldn't normally enounter. For example, there's a bug that wraps its (poisoned, but still-living) prey in a tight bundle to seal with its eggs as food. It has to put the bundle down to open the nest with its eggs, and if a researcher moves the bundle even just an inch or two away, the bug returns, finds that the bundle is not EXACTLY where it was left, and leaves to find a new victim.
And it's probably worth mentioning that even instincts live in the brain. Where else could they be? But you're right, most insects have brains with only a few thousand neurons instead of the billions you or I enjoy. But even humans have their share of instincts - walking and language use are two important instincts we all make use of daily, and babies show signs of trying pretty much from birth.
Yay instincts!

all living things think....
whether thinking is just for survival or it has some intelligence is a matter of evolutionary development....
