I'm on standby to see if any eggs or babies roam in the next few weeks ⭐️⭐️⭐️⭐️⭐️ ### ⭐⭐⭐⭐ Does the job. Apply minimal amounts *by on Reviewed in the United States 22 June 2026* Works great on roaches,ants, bed bugs I've tried it on. Don't over apply the dust,less is the best. It's takes a while to kill the pests, because of the minimal amount of insecticide they put in the product to make it undetectable to the insects. ## Frequently Bought Together - Ortho Home Defense Max Bed Bug & Flea Killer Powder, 12 oz. – Apply to Cracks and Crevices for Up to 8 Months of Control - Ortho Home Defense Max Bed Bug, Flea and Tick Killer with Comfort Wand, Bed Bug Spray, Kills Bed Bug Eggs, Fleas and Ticks, 1 gal. - Ortho Home Defense Max Bed Bug Trap, Detect Bed Bugs in Homes and While Traveling, 2-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/410441652-home-defense-max-bed-bug-and-flea-killer-powder-12](https://www.desertcart.pt/products/410441652-home-defense-max-bed-bug-and-flea-killer-powder-12) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-15*
