EZ OX Oxalic Acid Powder--the Go-To for OA Vaporization Mite Treatments

I have not used the EZ OX Oxalic Acid Powder yet (will need it in August), but this specific product was highly recommended by other experienced beekeepers for its high quality. HillCo was also the recommended source, and the order came quickly and was safely packaged. The little things do matter, thanks HillCo!
