Caution: Always use food-grade diatomaceous earth to avoid respiratory issues.
3. Garlic and Essential Oils as Repellents
The strong scent of garlic and certain essential oils (like lavender, tea tree, and eucalyptus) disrupts bedbugs’ sense of direction and deters them.
DIY Bedbug Spray Recipe:
- Mix 25 ml of lavender essential oil
- 50 ml of tea tree oil
- 1 liter of water
Spray on linens, mattresses, and into corners where bedbugs might be hiding.
4. High-Temperature Washing
Wash your sheets, clothes, and curtains at a minimum of 60°C (140°F) to kill eggs and larvae. If possible, tumble-dry them on a hot setting afterward.
Good to Know: For infested objects, seal them in airtight plastic bags and freeze them for 48 hours to kill the bugs with cold.
5. Seal All Their Hiding Spots
Bedbugs love cracks and crevices. Seal up holes in the walls, repair baseboards, and use anti-bedbug covers on your mattresses.

Preventing Another Infestation
- Vacuum high-risk areas (like beds, couches, and rugs) regularly.
- Don’t bring secondhand furniture home without inspecting it thoroughly.
- Check your luggage after hotel stays or public transportation travel.
- Use anti-bedbug covers on mattresses and pillows.
With these natural methods, you can successfully eliminate bedbugs and restore a healthy, chemical-free home environment!
