Input:
This product works great for protection against mosquitoes in Florida.

We spent last night camping in the Big Cypress National Preserve and after originally starting the evening with another product, and being bitten by mosquitoes, we switched to our old faithful DEET and were protected.

We will never use anything else.

We have been using this product for years and have never had a problem with leaking packages.
