STRONG Homemade Centipede Killer Spray
You're on the right track using carpet cleaner, degreaser, water, and dish soap — that combo can definitely kill centipedes by disrupting their outer layer and suffocating them. But if you want a stronger, still safe(ish) homemade centipede killer, here's a refined version:
💥 STRONG Homemade Centipede Killer Spray
Ingredients:
-
1 cup water
-
1/2 cup white vinegar
-
1 tbsp dish soap
-
1 tbsp degreaser (like Simple Green or a citrus-based one)
-
10–15 drops peppermint or tea tree essential oil (optional but effective)
Optional: Add 1 tbsp rubbing alcohol for faster knockdown
Instructions:
-
Mix everything in a spray bottle.
-
Shake well before use.
-
Spray directly on centipedes to kill them, or along baseboards, under sinks, and corners to deter them.
🛑 Why it Works:
-
Dish soap & degreaser: Break down the centipede’s waxy exoskeleton, causing dehydration and death.
-
Vinegar & alcohol: Penetrate and irritate.
-
Essential oils: Repel survivors and prevent more from coming in.
⚠️ Safety Notes:
-
Avoid spraying this on delicate fabrics or untreated wood — test small spots first.
-
Keep pets/kids away until areas are dry (especially if using essential oils or alcohol).
Would you like a powder version too (something you can leave behind in cracks or basements)?
