Mosquito Repellent that comes from Bacteria?

Mosquito Repellent
Anyone who’s been bitten by a mosquito knows how irritating they can be. The itch can last for days and can really disturb you from your sleep. So you decide to get rid of them using various methods including spraying your room full of mosquito repellent or applying generous amounts of a cream to prevent mosquito bites. Most of the time these don’t work or raise health concerns, so the alternative? A mosquito repellent made from Bacteria. Yes you read right.Bacteria.

A Mosquito Repellent made form Bacteria:

The mosquito repellent is in the form of a compound extracted from a particular form of bacteria. This so called new type of mosquito repellent is capable of preventing a mosquito bite at low doses as compared to other effective brands such as DEET and picaridin. This mosquito repellent extracted from bacteria is found to protect an individual from mosquitos that are known to carry the Zika virus, West Nile, Chikungunya, malaria and other diseases that effects millions of people across the globe.

The natural chemical so extracted form bacteria is called fabclavines and is still not tested suitable for humans. But according to researchers just knowing that there is a compound out there that could repel mosquitoes is enough to merit further exploration into the idea.

The Experiment to Find a New Kind of Mosquito Repellent: 

Researchers found out that these extracts from the bacteria did not kill mosquitos. But when sprayed on their food, they refused to eat it. A new experiment was thought of to test the bacteria compound’s potential.

Researchers used a skin like membrane that contained something to mimic blood as well as a number of cloth coverings to sit atop the skin like membrane. These cloth coverings would be coated with the repellents being tested out.

Researchers used DEET, picardin and plain water to test the efficacy of each in preventing a mosquito bite. Researchers then allowed the mosquitoes to feed for 30 mins by which time they would then freeze them and check for red substance that was used to mimic blood and those mosquitoes that remained unfed. The results showed that those mosquitoes that were around a repellent coated cloth did not eat anything. Proving DEET and picardin to be effective in warding off mosquito bites.
Researchers then tested the compound from bacteria and found that mosquitoes too did not feed when the cloth was covered with the bacteria compound. Then researchers compared the efficacy of DEET and picardin with the compound from bacteria in keeping away mosquitoes and found that the compound from the bacteria required 8 times and three times less compound than DEET and picardin in protecting one from a mosquito bite. Using less doses in the mosquito repellent means that the repellent will be much cheaper to make and consequently cheaper to buy.

Researchers are still not sure how this bacteria is a successful mosquito repellent. It may be just that the bacteria compound makes the food taste bad for mosquitoes.
