Why Are Maggots Suddenly Appearing in Your Trash Bin? Here’s What to Do

Make sure the lid closes properly.
Consider using sealed containers for particularly odorous food waste where appropriate.
If your local waste service provides separate food-waste collection, using that service can also help keep organic material out of a regular household trash bin.

The Bottom Line
Maggots in a trash bin are generally a sign that flies have found suitable organic material and environmental conditions for their larvae to develop. They are unpleasant, but the problem can usually be addressed through proper waste removal and thorough cleaning.

Keeping food waste contained, removing garbage regularly, and maintaining a clean, dry bin can make your trash container much less attractive to flies.
