Why wouldn’t it go away? Ever 5 seconds I would have to scratch my arm and everything I tried like putting a cross through it, applying tea tree oil and using the mosquito zapper, nothing would work! How could something so tiny cause so much irritation? It is small insect that sucks your blood. Isn’t that gross imagine all the germs it could be carrying. No wonder people get so sick. Mosquitoes carry diseases like malaria. That is why some people in other countries like Africa are getting so sick!Just imagine what a spider could do!
