EX4 is an effective insecticide and it can be used immediately upon application onto clothing, but we would not recommend doing so because firstly, of course your clothes will be wet, and we would recommend that the EX4 does not come in direct contact with your skin. It is vey important that the clothes are fully dried after treatment of EX4 onto clothing, or any fabrics, once fully absorbed the effectiveness and duration of each treatment will increase significantly keeping you protected for longer. We would recommend letting the clothing or fabric to dry for at least 2 hours before use. Please follow the instructions on the product packaging before use, and if you require further information please take a look at the Lifesystems.co.uk website FAQs. ## Frequently Bought Together - Lifesystems Ex4 Anti Mosquito Clothing, Footwear And Outdoor Gear Treatment - 350 ml Spray | Protect Against Mosquitoes, Midges, Biting Insects, Black - Jungle Formula Maximum Strength Insect Repellent Aerosol Spray (125ml - 50% DEET) - Up to 9 Hour Protection Against Mosquitoes, Ticks & Biting Insects - Mosquito Repellent for Travel & Domestic Use - Lifesystems Insect Repellent Expedition Maximum DEET Pump Spray | Repels Mosquitoes, Biting Insects, Ticks | Up to 8hrs Protection, Ideal For Any Destination Including Jungle Tropics, Silver --- ## 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.jp/products/49430213-lifesystems-ex4-anti-mosquito-clothes-and-fabrics-treatment-permethrin-spray](https://www.desertcart.jp/products/49430213-lifesystems-ex4-anti-mosquito-clothes-and-fabrics-treatment-permethrin-spray) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-14*
