1. The heat of boiling water kills the maggots on contact. Set a large pot of water over high heat for about 5 minutes so it comes to a boil. Once the water is bubbling, pour the water slowly and carefully over any areas that are infested with maggots. Within seconds, the water will kill the maggots so you’re able to get rid of any material they were feeding on without them spreading.^[1]

   • If the maggots are in the trash bin, close the lid to keep in the heat and more effectively kill an infestation.
   • Boiling water works best outside or in garbage bins. Avoid using this method on your walls or carpet since the heat and moisture can lead to structural damage and mold growth.

1. Salt quickly dehydrates maggots to control them. Take a scoop of rock salt and spread it liberally onto the maggots to coat them. Watch the maggots for a few minutes until they stop moving, and sprinkle more salt on them if they’re still alive after about 5 minutes.^[2]

   • Salt draws the water out of the maggots’ bodies and causes them to die of water pressure deficiency
   • Alternatively, use garden lime to help control maggots in your yard or garden.

1. Diatomaceous earth cuts into the maggot to kill it faster. Diatomaceous earth is a natural powder that sticks to the maggot to draw out moisture. Apply diatomaceous earth over the maggots so they’re completely covered. Wait about 5 minutes and check if the maggots are still alive. If they are, sprinkle a little more diatomaceous earth onto them.

   • Diatomaceous earth works great for treating along baseboards, deep in carpet fibers, inside of your garbage cans, or around your yard.
   • Diatomaceous earth can cause irritation, so avoid using it anywhere where kids or pets could get into it.^[3]

Alternatively, look for a permethrin pesticide, which helps get rid of maggots and fly eggs. Apply the spray directly onto the maggots and the surrounding areas to ensure you kill all of them.^[6]

   • Chemical insecticides cause eye and lung irritation, so wear safety glasses and a face mask while you’re using them.
   • Permethrin and synthetic pyrethroids can be fatal to cats, so avoid using them near your pets.^[7]

To prevent maggots from getting in your trash, keep all your trash tightly sealed in bags so they don’t leak. Whenever there’s a spill, wipe it up right away to prevent infestations. Other things that work well to prevent maggots are:^[8]
