People think that vitamin B 1 can repel mosquitoes, which originated in western countries in the 1940s. Because vitamin B 1 has a light smell and a bitter taste, people take it for granted that blood will have the same taste after spraying drugs on the body surface or taking drugs orally, which can deter mosquitoes.

Current research has confirmed that B vitamins can't repel mosquitoes. Mosquitoes have different odor preferences from humans, and the disgusting vitamin B 1 will not affect mosquitoes. The smell of vitamin B 1 does not repel mosquitoes, and because vitamin B 1 is unstable in water, it is easy to decompose due to heat and light. Therefore, it is not advisable to dissolve vitamin B 1 in water as a mosquito repellent.
