Here are some ways to kill maggots instantly:

• Boiling water: Pour boiling water over the maggots to kill them instantly. Boiling water causes protein coagulation and kills maggots naturally.
• Vinegar: Dilute vinegar with an equal amount of water and spray the solution directly onto the maggots for effective results. Its acidic nature helps break down the protective coating of maggots, leading to their demise.
• Salt: Cover the maggots food source with salt to eliminate their access to water. This method tends to be effective when the pests are confined to a small area.
• Diatomaceous earth: Sprinkle diatomaceous earth powder in your trash can to dehydrate and kill maggots.
• Bleach: Mix equal amounts of bleach and water together and pour it over the maggots to kill them. Alternatively, 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.

Its important to note that maggots can be resilient and challenging to eliminate, so its best to identify and eliminate the source of the infestation to prevent their growth and potential health hazards.
