Most specimens – those with relatively hard bodies – can be killed by placing them in the freezer for a few minutes. Wrap them lightly in tissue paper and place them in a small box, vial, or other sturdy, crush-proof container.
Soft-bodied specimens, such as caterpillars, grubs, and other immature arthropods, can be killed by placing them in hot water. Bring a small pot of water to a boil, then remove it from the stove and drop the insect into the water. Remove it after a few seconds have passed. Usually no more than one minute is required. Place the insect in a vial of alcohol.
Spiders, ticks, and many other arthropods can be dropped directly into a vial of alcohol.
Do not send specimens taped to a piece of paper or tossed into a plastic bag.
