Disadvantages of using ant repellent.

One chemical found in many ant repellent is DEET( N,N- diethyl -m- toulamide ) .A 2009 study found that DEET can interfere with the activity of enzymes that are vital for the nervous system to function properly. In the study,the researchers have found that DEET blocked the enzyme cholinesterase, which is essential for transmitting message from the brain to the muscles .The study, conducted by the institute of Development Research in France and published in the journal BMC Biology, found that the chemicals that interfere with the action of cholinesterase can cause excessive salivation and eye-watering in low doses, followed muscle spasms and ultimately death.
