This is a Big Difference. Which is correct please?** A: It's extremely difficult to give an accurate answer on this as depends if the air is dead still or not. All I can say is that this bit of equipment has proved itself several times when battling with extremely aggressive Scottish midgies. **Q: Can you refill the Butane Gas Cartridges?** A: Have seen someone on YouTube doing it but I wouldn't advise it.. **Q: How to use it? Does it stand in an area you sit in while camping? Or do you have to hold it?** A: We usually put it on our picnic table and that protects the area we sit. You don't need to hold it we lay it flat with the black grid facing up. We have tried using on the move and it doesn't work well like that but when in camp it works really well. **Q: Can I use this inside a summerhouse, with the doors open?** A: The instructions (inside the box) state that the device should not be used in a confined space. It There is risk attached to using in a summerhouse even with the doors open. I would suggest asking the manufacturer for further guidance. I now use a plug in device from Jungle available from Amazon or currently on offer in Wilko. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 100% recommended *by G***M on 10 October 2024* Best of the best! Value for money! Was our life saver from moscitos. Awesome ! ### ⭐⭐⭐⭐⭐ Excellent *by A***S on 12 August 2025* Excellent ### ⭐⭐⭐⭐ No flies on this (soz) *by R***P on 24 July 2021* Used a fair bit now. Lights easily, only gone out once. I think it works, certainly not been bitten, including Scotland in summer. Relatively chunky and heavy when backpacking, but worth it for no bites when sprays don't work ## Frequently Bought Together - Thermacell MR300 Mosquito & Midge Protector; Includes 3 x 4hr Mats & 1 x 12hr Cartridge; Easy to Use, Highly Effective; DEET-Free; No Spray; 20 sq m Zone of Protection - Graphite - Thermacell Midge and Mosquito Protector Standard Refill Pack Compatible All Thermacell Fuel Powered protectors --- ## 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.vn/products/92163958-mr300-portable-mosquito-and-midge-repeller-20sqm-deet-free-protection](https://www.desertcart.vn/products/92163958-mr300-portable-mosquito-and-midge-repeller-20sqm-deet-free-protection) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
