I have had a recent spout of black files in my shed but it has flammable materials.** A: No problem but I would suggest placing the bomb on a saucer just in case!! They work incredibly well. **Q: Can this be used in a crawlspace under kitchen, would be sitting about 25cm beneath floorboards.** A: Think it would be ok, as long as you put it on something that won’t burn, as it starts off hot (as you have to light the wick). I used it successfully in a small area by taping it to a pole so I could get it into the ‘crawl space - worked really well, left it to fume for a few hours, all good. **Q: How do you use these, i have drain flies. How can i kill them** A: you light them like a small candle/firework and after a small amount of burning they release the smoke that kills things ,you could float them on a small foil pie tray or something like that .They work best where the area is sealed though (room with door closed etc ) ## Frequently Bought Together - Pest Expert Cluster Fly Killer Smoke Bombs 4 x 3.5g - Formula 'P' Fumer Cluster Fly Bomb (HSE approved and tested – professional strength product) - Pest Expert Cluster Fly Killer Spray Treatment 1Ltr - Formula 'C+' Advanced Maximum Strength Fly Spray, Fast-Acting & Long-Lasting Control, Professional Strength Approved for Amateur Use - Pest Expert Formula ‘P+’ Cluster Fly Killer Fogger Treatment 4 x 150ml – Maximum Strength Fly Bombs for Fast-Acting Effective Control, Professional Strength for Approved Amateur Use --- ## 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.id/products/48628711-pest-expert-cluster-fly-killer-smoke-bombs-4-x-3](https://www.desertcart.id/products/48628711-pest-expert-cluster-fly-killer-smoke-bombs-4-x-3) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-09*
