Why flies investigate bins
Flies are attracted to decomposing organic material. Small leaks or scraps left after pickup may provide odor and moisture cues.
How maggots appear
Maggots are fly larvae. They may appear when flies reach suitable organic material before or inside the bin.
Cleaning reduces attractants
Professional cleaning removes the stuck on residue that can contribute to odor and pest attraction. It does not replace secure bags, a closed lid, or general property pest control.
