Try painting the incredible itch with nail polish, you can use clear if it's not Halloween.This also works great on chiggers. Just got back from Cayo Mountains and Am. Caye with every bite available except for the vampire bats. Seed ticks, mosquitos, no-see-ems, flies, chiggers. Then there was those trees in the jungle that leave a reaction like poison ivy. All worth it. Fantastic country, wonderful people!
