How to Send Adult Honey Bees

·         Send at least 100 bees and if possible, select bees that are dying or that died recently. Decayed bees are not satisfactory for examination.

·         Bees should be placed in and soaked with 70% ethyl, methyl, or isopropyl alcohol as soon as possible after collection and packed in leak-proof containers.

·         USPS, UPS, and FedEx do no accept shipments containing alcohol. Just prior to mailing samples, pour off all excess alcohol to meet shipping requirements.

·         Do NOT send bees dry (without alcohol).

How to send brood samples

· A comb sample should be at least 2 x 2 inches and contain as much of the dead or discolored brood as possible. NO HONEY SHOULD BE PRESENT IN THE SAMPLE.

· The comb can be sent in a paper bag or loosely wrapped in a paper towel, newspaper, etc. and sent in a heavy cardboard box. AVOID wrappings such as plastic, aluminum foil, waxed paper, tin, glass, etc. because they promote decomposition and the growth of mold.

· If a comb cannot be sent, the probe used to examine a diseased larva in the cell may contain enough material for tests. The probe can be wrapped in paper and sent to the laboratory in an envelope.
