Review: It works - Second purchase of this as it works so well. I wish I had a photo of the part of our tent that I missed spraying as it was completely black with midges where the rest of the tent was clear. I have sprayed it on our merino clothing and water-resistant hiking trousers and no adverse effects. One bottle covered our MSR Elixir2 tent - inner and outer, plus both sides of the ground sheet, two pairs of trousers, four merino tops, possibly two gotetex shell jackets and our gloves. We still have a drop left but it looks like we need one bottle per trip.

**Q: Does the product state a use by or expiry date, if so what is its approx lifespan?**
A: I can't find any expiry date on the batch we have in stock, but there is an indication that the liquid should be used within 24 months of opening.

**Q: How far in advance should you spray your clothes?**
A: Hello, thank you for your question. 

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.
