Buy Insect Repellants online and in store from BCH Camping UK. We stock a good range of Lifesystems repellant, sprays in 50ml and 100ml bottles. Lifesystems repellants are made using a chemical called Deet. We sell either 50% Deet repellant and 100% Deet repellant. The difference is that whilst the 100% Deet is much stronger and probably only needs to be used once a day, it has been known to iritate sensative skin, or those people with skin problems. 50% Deet will need to be applied more often, but because it has half of the Deet it makes it much kinder on the skin. 50% Deet is our biggest seller, but we have lots of customers who use 100% Deet and never have a problem with it. Buy Lifesystems Bite Relief Click. We are all familiar with the itch you get after being bitten, the bite relief click help reduce that itch. Simply click on top of the bite and a tiny electric shock takes the itch away. Buy Tick tweezers from BCH Camping.
