There are several ways to kill maggots on contact, both naturally and chemically. Here are some effective methods:

• Boiling water: Pouring boiling water over maggots is the most impactful way to kill them quickly. The heat of boiling water causes protein coagulation and kills maggots instantly.

• Vinegar solution: Pouring a vinegar solution on maggots is another natural way to kill them instantly.

• Salt: Salt is a cheap and simple way to draw water out of nearly anything in the world, and it can kill maggots. You can either pour granulated salt directly onto maggots or create a saltwater solution that can be poured or sprayed across food waste or a garbage bin.

• Bleach: Bleach can be an effective method to kill maggots on contact. Mix equal amounts of bleach and water together and pour it over the maggots or use a spray bottle to apply the solution liberally onto the infested area. Let the bleach sit for about 30 minutes before disposing of the maggots.

• Diatomaceous earth: Diatomaceous earth is a natural powder that sticks to the maggot to draw out moisture. Apply diatomaceous earth over the maggots so theyre completely covered.

• Soap and water: A simple solution of soap and water can be effective in killing maggots. Create a soapy mixture by mixing dish soap or any mild detergent with water. Pour or spray the solution directly onto the maggots, suffocating and killing them.

Its important to note that the most effective way to get rid of maggots is to eliminate the source. Keeping kitchens and other surfaces clean, using fly traps, and encouraging natural predators like birds and reptiles can help to keep maggot populations in check.
