Named Storm Beryl was a rain event here in Puerto Rico. The rain has passed, and the mosquitos have come out in swarms… they are ravenous. We have mosquito netting on all the hatches but, these guys are relentless so, I have pulled out the best mosquito repellent device for boats. No smell and no noise this silent but deadly is really all you need to eliminate mosquitos on your boat. Stock up on the affordable cartridges because you will become dependent on these devises and don’t want to be left smacking your head in the middle of the night, if you know what I mean neeeeeeeeeeeeee!
