Insect Repellent

There are four active ingredients that are scientifically proven to repel mosquitos and three of these are synthetic, or chemical based: DEET, IR3535 and Icaridin. Looking at repellents containing these ingredients we found that prices varied considerably – even in ones containing the same percentage of active ingredients. For example, we found a Wilko repellent pump spray costing £3 for 100ml that had the same level of protection (50% DEET and 1% PMD) as a Boots repellent pump spray at £8.65 for 100ml – nearly three times the price. DEET is one of the most common options you'll find, and for good reason: it's highly effective at keeping mosquitos away, even in areas where they carry diseases like malaria. Look out for multi-buy deals; shops where you can accrue loyalty points and own brands. They're often cheaper for the same active ingredients. A simple spray is usually cheapest. Roll-ons or compact bottles are likely to be pricier. For example, a pump spray bottle of Boots Repel Maximum DEET & PMD is £8.65 for 100ml but a roll-on version of the same product is £5.50 for 50ml – that's £11 per 100ml. Make sure you check the label to see if the product is the right strength for your needs. Most products use their own systems, but should be clear on whether they are 'tropical strength' or not. Check with a pharmacist if you're unsure.
