These quick and easy test kits for European Foul Brood (EFB), take only minutes and are as reliable as Standard EFB laboratory tests. No more waiting for the Beltsville Bee Lab to get back to you after sending in your sample. Please remember that while EFB is treatable, the medication requires a prescription or veterinary feed directive. Should you discover that your bees have EFB, please contact us, and we can refer you to a local veterinarian.
