Sending insects to a diagnostic lab takes some preparation. Here are some considerations and steps to take before you mail any samples.

• Complete, intact and well-preserved specimens offer the best chance for identification.
• Most insects should be preserved immediately after collection.
• Dried and unprotected insects are easily crumbled during mail processing.
• Do not attach insects to tape. The insect will likely be destroyed when removed from the tape.
• Several specimens should be included, if possible.
• Most specimens can be killed and preserved in glass or plastic jars containing 70-90 percent ethyl or isopropyl (rubbing) alcohol.
• Do not send insects in water.
• Fragile insects (butterflies, moths) should be killed in a freezer. Store in a sturdy container lined with tissue paper. Do not use alcohol.
• Pests on plants such as mites, thrips, aphids, scale and other fragile insects should be sent in on the diseased plant.
• Send small caterpillars, grubs and maggots live in a plastic bag with some of the host material, if possible. It may be necessary to rear some of these to the adult stage for positive identification.
