Be very careful with deet sprays. While effective, deet is damaging to many synthetic fabrics/plastics.
You don't have to go to Amazon for it. Great Outdoors, Snow & Rock and most other outdoors stores will stock it.

Malaria isn't the only nasty you can get from mosquito bites. I'm allergic to them and affected areas swell up alarmingly (can't get clothes on sometimes); mozzie net is well worth it for a comfortable nights sleep.certainly not a malaria risk there and you won't need things like mosquito nets
