The main predator is likely cars in this case. Those numbers won't be decreasing, and bug numbers likely won't be bouncing back

I was under the impression the main predator was insecticides.

This isn’t a simple two-species system. If insect population collapse were to cause a human population collapse, I think the number of cars (and wind turbines, and insecticides) would follow, possibly early enough to prevent full extinction of insects.
