The bugs that appear on the breakers are usually food residues from the breakers. Then these food scraps may grow maggots, or may be the larvae of some moths. These larvae reproduce in the food scraps. But these bugs are definitely harmful if you eat them, so you still need to sanitize the wallbreaker. Clean out the bugs. You can sterilize it with high heat and then use it after sterilizing it. Then it will be fine.
