Prevention is considered one of the most desirable approaches to a containment measure.

The grubs are stubborn when they get into your home, and getting rid of them can be costly and unpleasant. However, cleaning the used surfaces after eating can be effortless. It can save you the embarrassments you may experience with the larvae when you are visited by your friends or families, even worse when they invade your commercial garage.

Additionally, when keeping any food in your garage, ensure it is safe in an airtight container or entirely covered to keep maggots away from getting into the food. Such a practice will limit the chances of the larvae getting into the food and their potential habitation of the garage.

Ensure your garbage bins are tightly sealed

Sealing your garbage bins prevents the entry of larvae and reproduction.  Most garages have containers that can form the breeding sites for the flies, resulting in a heavy infestation by maggots over time. The last thing you would want to do is, therefore, to leave your garbage unsealed.

If you do not have appropriate sealing materials for your garbage, you can also opt to remove them and dispose of them each day before you leave your garage. The garbage bins left in the garage for a long time can breed the maggots, but when they are emptied each working day, the larvae are deprived of the breeding sites or a place to live.
