Lifesystems Insect Bite Relief Clicker soothes the discomfort and itching of insect bites by inhibiting the histamine build up under the skin.

All you need to do is click the device 5-10 times around the area of the bite to help neutralise the toxicity, reducing any inflammation and swelling. The removal of the urge to scratch ensures that a bite does not become septic.

These Lifesystem insect bite relief clickers have been clinically tested and approved by doctors, with each one capable of treating up to 1,000 bites at 10,000 clicks. No batteries are involved, so they also have no sell by date.

They are  ideal for travellers to tropical countries or for camping in areas with a high insect infestation, and should form part of your summer first aid kit.
