We’ve taken steps to control mosquitos and it seems that the problem is greatly reduced over the past couple of decades. The marina stocks both DEET and eucalyptus-based repellents.
Which mosquito repellents work best?
CDC recommends the use of products containing active ingredients which have been registered with the U.S. Environmental Protection Agency (EPA) for use as repellents applied to skin and clothing.
“Of the products registered with the EPA, those containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection.” https://www.cdc.gov/westnile/faq/repellent.html
