The thick exoskeletons of insects provide protection against direct contact with insecticides.

Explanation:
The insect’s outer shell acts as a protective barrier to chemicals. The cuticle, especially when thick and waxy, slows or limits how quickly a pesticide can penetrate into the insect’s body. Because of this barrier, a thick exoskeleton provides some protection against direct contact with insecticides. It’s important to note that this protection isn’t absolute—many pesticides are formulated to penetrate the cuticle or act through other exposure routes, so absorption can still occur. But in general, the thicker the exoskeleton, the more it reduces immediate penetration from contact exposure.
