I've heard that about the Bounce sheets. Does it have to be scented or does unscented work as well?
I don't know. Last week in the Carolina low country I was using the scented sheets and didn't receive even one mosquito bite.
Citronella is very good against mosquitoes. I would dilute it when applying to the skin, with something like olive or almond oil. Or even water. Use drops on clothes. It can be mixed with pennyroyal but be careful with pennyroyal as it is rather toxic so it shouldn't be applied to the skin unless very diluted. These oils are strong, but when used in dilution, are effective (in my experience) but really need to be applied thoroughly.
Bounce - ugh! :-(
