Bed bugs are a nightmare, but you don’t need harsh chemicals to eliminate them. These natural solutions kill bed bugs on contact, destroy eggs, and prevent reinfestation—without poisoning your home.
Why Natural Remedies Work
✔ Heat treatment – Bed bugs die at 120°F+ (49°C+)
✔ Diatomaceous earth – Dehydrates and kills them in 48 hours
✔ Essential oils – Disrupt their nervous system (peppermint, tea tree, lavender)
✔ Alcohol spray – Dissolves their protective coating

Step-by-Step Elimination Guide
1. Deep Clean & Heat Treat
- Wash & dry all bedding/clothes on HIGH heat (120°F+ for 30 mins).
- Steam clean mattresses, couches, and carpets (focus on seams & edges).
- Vacuum thoroughly, then seal & discard the vacuum bag.
2. Apply Diatomaceous Earth (DE)
- Sprinkle food-grade DE on mattress edges, baseboards, and cracks.
- Leave for 3-5 days, then vacuum. (Safe for pets once settled!)
3. Make a Killer Essential Oil Spray
- Mix:
- 10 drops tea tree oil
- 10 drops lavender oil
- 1 cup water
- ½ cup rubbing alcohol
- Spray on infested areas daily (repels & kills bugs).
4. Trap Remaining Bugs
- Place bed bug interceptors under bed legs.
- Cover mattress with a bed bug-proof encasement.
⚠️ Critical Tips for Success
- Repeat treatments for 2-3 weeks (eggs hatch in 6-10 days).
- Avoid clutter – Bed bugs hide in cracks, books, and electronics.
- Check secondhand furniture before bringing it inside.
- Don’t use bleach – It stains but doesn’t kill eggs.
Call an exterminator if:
- The infestation is severe (large colonies in walls).
- DIY methods fail after 4 weeks.
