How do bug sprays work?
Special repellency versus contact repellency
Mosquitoes are attracted to humans because, simply, we are their food source. Yes they can get food from other sources such as plant nectars however female mosquitoes, the ones who propagate and continue to mosquito race, depend on blood to grow their eggs. Typically, both male and female mosquitoes feed on nectar and plant juices, but in many species the mouthparts of the females are adapted for piercing the skin of animal hosts and sucking their blood as ectoparasites(6).
The way products with DEET in them can work is that they create contact repellency: basically, a mosquito lands on the chemical, which could be on your skin, the mosquito gets tingly from the toxicity and leaves. Special repellency essentially creates a barrier the mosquitoes will not penetrate (this is how products like Aromaflage function). Spatial repellency protects people from insect-borne diseases by reducing contact between disease-spreading insects and humans.(1) Some studies suggest that combinations of certain spatial repellents might provide significantly greater protection.(4)
As with all things you put on or in your body, it is important to understand what the active ingredients are and what potential side effects (toxicity via inhalation, neurological effects, personal health effects, skin irritation, etc.) they may have.
Aromaflage is on a mission to create a novel solution to a real problem affecting millions of people. Mosquitoes carry not only annoying, but also deadly diseases. Most answers to these pesky beasts are toxic and noxious containing harsh chemicals like DEET and can potentially cause long-term health issues. Other natural solutions smell bad. Our solution is focused on a healthy alternative to protecting ones family (while also smelling pretty darn great).
