There are several DIY home remedies that can kill bed bugs instantly. Here are some of the most effective ones:

• Rubbing alcohol: Rubbing alcohol can kill bed bugs instantly. You can spray it directly on the bugs or on the areas where they are hiding.

• Diatomaceous earth: Diatomaceous earth is a chemical-free powder that can eliminate different types of pests, including bed bugs. It dehydrates the bed bugs, which kills them off. It may take up to a week before you see results. Be careful when using diatomaceous earth as it can be easily inhaled. Use a face mask to prevent this and make sure that you use gloves too.

• Baking soda: Baking soda dehydrates the bugs by removing moisture. You can sprinkle a light layer of baking soda on areas you think these critters are staying in. Let the powder sit for a week before using your vacuum cleaner to suck up everything. You will need to do this often until there are no bugs or eggs left.

• Heat or cold: Temperature is an effective way to get rid of bed bugs in a mattress or other important area. With that in mind, gather affected bedding or clothing and wash it in very hot water for 30 minutes. Once the wash cycle is done, dry the items in your dryer on the highest possible heat setting for at least 30 minutes. Alternately, put affected items in a freezer that is at least 0 degrees Fahrenheit. Leave them there for four days to make sure all bed bugs are dead.

• Tea tree oil: While tea tree oil cannot kill all bed bugs on contact, it is a strong deterrent and masks the smell of sweat, which bed bugs are attracted to. You can spray undiluted tea tree oil on your bed sheets and furniture to repel bed bugs.

Its important to note that while these remedies can be effective, they may not completely eliminate a bed bug infestation. Its best to consult a professional pest control service for severe infestations.
