If you use this makes sure to spary clothing before you put it on and to allow it to completely dry.DEET is great. But at the end of the day it is primarily a repellent. There is a better chemical called permethrin. This stuff actually kills when bug land on it as well as being a repellent. Its safe to everything else except cats. The military uses it on their fabrics because it will lasts for a week or more, including multiple washings.
The one hitch, it has not been released for use on skin. There are a number of studies that show it is safe, but still... not released for skin. So I put it on my shirt, pants or shorts, shoes socks and hat, then use deet on the exposed skin.
Have fun in Costa Rica! They carry a spray called jungle juice that works well. I'm not sure It will last the whole day thru, I sweat alot and that will reduce its effectiveness! Be preparred to sweat! the humitity and heat index their is unreal! Have a great time! By the way, Christine, my wife and I tried that Skin so soft one night, and all the insects that did land on us seemed to get stuck and wiggle around on our skin!Thanks folks!!! I am taking notes and getting ready.... Costa Rica, we are coming and we will be prepared.
Hell, that's all I need. It'd be my luck I'd lather up with a little K.C. Masterpiece and some bear or nasty fat chick on a hoveround would chase me down and eat me...shoot man, you're in the jungle. schlack on some bbq sauce and get savage.
