Am allergic to sand fleas, recommend place in Belize to avoid them?

Usually there are NO sand fleas on AC from January through end of summer.
I have been affected by them at all times of year in Placencia and found that Hopkins was quite nasty as well.
Haven't noticed much problem in Caye Caulker either, but it's not just about location it is about weather/time of year.
Come to AC or CC this winter and you should be fine!

Punta Gorda and any place on the interior of the country is the perfect location to avoid sand fleas any time of the year. Avoid areas with SAND.

Or wear a heavy coat of skin so soft / baby lotion. They seem to find me all year round in AC - usually sundown....

Coconut oil works well too. Glorious Belize brand at Greenhouse is really nice.
