Except maybe mosquitoes.
We tend to reach for DEET and other chemical sprays as the most common option for protection against mosquito bites. But exposure to these products can lead to some uncomfortable and even dangerous side effects.
Here are some facts about DEET you may not be aware of:
1) The CDC advises that DEET be sprayed on clothing only, not directly on skin, as it can be absorbed into our bloodstream, and then processed by the liver. It should not be sprayed over cuts, wounds, or on broken or irritated skin. If applied directly to flesh, it must be washed off with soap and water as soon as possible.
2). DEET and other chemicals are not suitable for young children, as spray can get on their hands, putting them at risk for ingestion when their hands go in their mouth. There have also been concerns about seizures and toxic encephalopathy in children exposed to DEET, based on certain reports and studies.

4) While most reports say small amounts of DEET should be safe, studies regarding toxicity and long-term health problems associated with its use (such as cancer) are limited, or else provide conflicting evidence. Some are inconclusive.
“Scientists have not yet studied whether DEET in the air can be absorbed into your lungs after inhalation. It is absorbed through the skin and digestive tract, so it is likely that DEET can also be absorbed through the lungs and into the blood.” - ATSDR (Agency for Toxic Substances & Disease Registry) associated with CDC, 2015.
5) No studies have been conducted on the cumulative effect of DEET and bug repellents combined with other chemical products commonly used, such as sunscreen, moisturizer, etc.
Given the risks and conflicting information available, many are looking for a safer, non-chemical option when it comes to repelling mosquitoes.

The nopixgo® band uses a series of mild electromagnetic waves to change the mosquito’s behaviour. The insect identifies these signals as a storm warning, and as its focus changes from feeding to seeking shelter, it becomes much less aggressive about biting.
The band’s signal has a 2-metre radius and it runs on a long-life rechargeable battery that lasts up to 5 days. It can be worn on the wrist or attached to gear, and is available in six colours: Grey, Blue, Green, Orange, White, and Pink.

Mosquito-borne viruses are a legitimate and increasing concern, as is the toxic load of combining chemical ingredients. If you’re uncomfortable using DEET repellents or have experienced sensitivities from chemical products, the nopixgo® wristband is an amazing non-toxic, long-term solution in the prevention of mosquito bites.
