Just about every lodge or camp provides mosquito nets in their rooms. Usually, a room attendant will prepare the bed (while you are having dinner) by folding down the mosquito net and spraying insect repellent. If you are worried about the mosquitoes in your room, you can always try and ask for insect spray.

Many places located at high altitude have little mosquito activity during the night because temperatures can be very cool. Mosquitoes tend to be most active in the early evening, so wear repellent on your exposed skin, and protect yourself by wearing long sleeves, long pants, and socks.
