Home Remedies for Bed Bugs: Diatomaceous Earth, Tea Tree Oil and More

When bed bugs appear, many people search for natural or home remedies: diatomaceous earth, tea tree oil, baking soda, lavender, vinegar and more. Some have a little science behind them, others very little. Most cannot eliminate an established infestation on their own.

This guide sorts common remedies by what they may do and what to watch out for.

The short answer

Home remedies can sometimes kill or deter a few bed bugs, and some, such as heat-drying laundry and vacuuming, are genuinely useful as part of a plan, but most natural oils and powders do not reliably eliminate bed bugs, cannot reach all hiding places and do not stop eggs hatching. Some remedies carry risks, such as inhaling dust or skin irritation. For an infestation, professional treatment is far more dependable, and home measures work best as support.

Remedies that genuinely help

• Hot washing and high-heat drying: Kills bed bugs and eggs on fabrics when done properly.
• Vacuuming: Removes bugs and debris from seams and crevices. Dispose of contents outdoors.
• Steam: Can kill bugs on contact in seams and furniture when used correctly.
• Mattress encasements: Seal in bugs and remove a hiding place.
• Decluttering: Reduces hiding spots.

Remedies with limited or uncertain effect

• Diatomaceous earth: A fine powder that can damage insects' outer layer. It works slowly, only if applied thinly and kept dry, and does not reach bugs in deep hiding places. Use only food-grade or products labelled for the purpose, and avoid breathing the dust.
• Tea tree oil and other essential oils: May repel or kill a few on contact, but effects are short-lived and unreliable. Undiluted oils can irritate skin and harm pets.
• Baking soda: Little evidence of effectiveness.
• Vinegar and rubbing alcohol: Can kill bugs on contact but have no lasting effect, and alcohol is flammable.
• Lavender, peppermint and similar scents: May deter a little but do not control infestations.

Risks to keep in mind

1. Dust from powders can irritate the lungs, particularly for people with asthma.
2. Essential oils can be harmful to pets, especially cats, and irritate skin.
3. Flammable substances near heat or flames are dangerous.
4. Repellent remedies can scatter bugs and spread the infestation.
5. Delay allows the infestation to grow.

A sensible approach

1. Confirm it is bed bugs.
2. Use the helpful basics: washing, heat-drying, vacuuming and encasements.
3. Avoid remedies that scatter bugs.
4. Book professional treatment without long delay.

When to call a professional

If you still see bed bugs or bites after a couple of weeks of effort, call a professional. The infestation is likely beyond DIY.
