Review: 250+ miles hiking across Scotland, zero ticks - I’ve hiked and wild camped over 250 miles across Scotland in prime tick territory, in prime tick season, with this stuff on my gear, and not a single tick. Others around me were finding them frequently, so either this stuff works, or the ticks took one look at me after a few days wild camping and thought, “No thanks.” I’m choosing to credit the spray! Just make sure to spray your gear properly and let everything air dry fully before setting off. I treated my boots, trousers and backpack. In terms of longevity, I’m sure machine washing will reduce effectiveness, but for my longer expeditions, where frankly I’ve been a bit feral and operating somewhere between “outdoorsman” and “bog goblin”, I haven’t needed to top it up, and it has provided protection right through to the finish line. I know some people are wary of using chemical protection treatment, and I completely get that, but personally I think the trade-off is worth it when the alternative is potentially picking up Lyme disease. Obviously this doesn’t replace the need to check yourself frequently for ticks, but it has been an excellent layer of protection and I wouldn’t venture out without it now. Highly recommend.

A: It should not stain clothing,if it is cotton, rayon or other nylon clothing could have a problem, if it is on your hands and you touch plastic it would mark it

**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.

### ⭐⭐⭐⭐ Effective but smelly
*by A***Y on 19 January 2026*

As someone who seems to attract every biting insect within a mile, having sprayed this on my outdoor gear, I seem to have avoided getting bitten by ticks and mosquitoes the past year on numerous hikes. Though it works, the smell of the product is quite awful and I'm not sure I'd use it again.
