I’d get one room fly free and then turn around and they’d be in another room so I needed to do something drastic! These flies get absolutely EVERYWHERE! And all it takes is just 1 fly and the next day you’ll have hundreds more. And those hundreds more lay more and more eggs etc etc. (They can lay up to 500 eggs a day (each)!!) so it’s important to get every single last one in order to solve the problem. Anyway, nothing was working. I tried lots of different methods, sticky paper things that you hang from the ceiling, sticky window/wall stickers, natural home made and store bought ‘traps, and regular fly sprays but AGAIN nothing worked, (regular fly sprays don’t get these types of flies because they are too small for it to take effect). So I tried this spray ONCE in every room of the house and it’s killed them all completely. No flies at all now. Not even 1! It does smell awful, but it definitely works! I’d advise you to close all windows, spray the entire room then shut the door and leave the room otherwise the smell will choke you. It is a sort of citrus zesty smell but mixed with the chemicals, the smell will choke you if you remain in the room for too long. But rest assured it does the job once and for all!I also don’t grudge paying the price of £11 because it does kill them ALL. I read the reviews thinking it’ll probably be a waste of money but it definitely isn’t! And I’ve still got half a can left incase they come back next summer. ### ⭐⭐⭐⭐⭐ Seems to have worked. *by C***L on 27 February 2025* Seems to have enough eradicated a mystery bug which has been biting us. --- ## 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.us/products/77594398-powerful-insect-killer-spray-300ml-aerosol-instant-kill-for-wasps](https://www.desertcart.us/products/77594398-powerful-insect-killer-spray-300ml-aerosol-instant-kill-for-wasps) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-09*
