A powder version Best All-Around Bug Killer

Absolutely — a powder version can be even more effective for long-term centipede control, especially in places like:

• Baseboards

• Under sinks

• Behind appliances

• Basement cracks

• Carpet edges

Here are a few excellent homemade powder options that are safe and powerful:

🌿 1. Diatomaceous Earth (Food Grade) — Best All-Around Bug Killer

What It Does:

• Shreds the exoskeleton of centipedes and other insects, causing dehydration and death.

How to Use:

1. Lightly dust along baseboards, cracks, under furniture, and in corners.

2. Avoid thick piles — a light, barely-visible dusting works best.

3. Leave for several days or weeks, then vacuum and reapply if needed.

🟢 Safe for pets and kids if it’s food grade — just avoid stirring it up into the air.

🔥 2. Baking Soda + Cornstarch + Essential Oil Powder

Ingredients:

• 1/2 cup baking soda

• 1/2 cup cornstarch

• 10–15 drops peppermint or tea tree oil (optional)

Instructions:

1. Mix the dry ingredients in a container.

2. Add essential oil drops, mix thoroughly until evenly scented.

3. Sprinkle around affected areas.

🎯 Baking soda is mildly abrasive and drying; essential oils repel.

🧂 3. Borax + Baking Soda Powder (Aggressive Option)

Not recommended if pets/kids are present — borax can be toxic if ingested.

Ingredients:

• 1/2 cup borax

• 1/2 cup baking soda

Use:

• Dust into crevices and corners.

• Great behind heavy furniture or appliances where bugs travel but kids/pets don’t go.

Bonus Tip: DIY Powder Dispenser

Use an old spice shaker or a mason jar with a lid poked with small holes for easy, controlled dusting.
