What is a Mosquito Patch Repellant?
MosquitoPatch is a trans-dermal patch delivering sufficient doses of thiamine (vitamin B1) directly to the dermal or skin layer of the human body to act as a mosquito repellent.  Through this application, thiamine can move through the skin directly into the bloodstream and be circulated throughout the body before being excreted again through sweat.  Not all mosquito repellant works, they are designed to mask the body’s natural scent, which in theory should stop the bugs finding you appealing. These products offer a temporary solution but need to be re-applied constantly, and are not always effectively.

This may seem a strange question to ask. However, it is critically important. There are thousands of mosquito species worldwide. Some are far more important as nuisance-biting pests than others. Many don’t even bite humans. The vast majority of mosquito repellent tests published in the scientific literature use Aedes aegypti (the dengue/yellow fever mosquito). This is pretty much the lab rat of the mosquito world. It is a great species to work with as it is a day-biting species and has a relatively consistent biting rate. Testing a repellent against Aedes aegypti is pretty much the way to go. In malaria prone regions, testing against the malaria-vector and avid nuisance-biting species Anopheles gambiae is useful too.

If, however, a repellent is tested against a species such Culex quinquefasciatus, a species generally associated with bird-feeding, it is difficult to be confident with the results. We have this species is colony and whenever it is used for repellent tests, we get greatly different results. For example, in our testing of a botanical-based topical...
