    Pest ID

    Do you have a pest problem or a pest you’re interested in and want to know what it is or more about it?   Diagnostic Lab can help identify pest, and provide management suggestions if needed.


    Directions on how to send in samples or photos for identification:


    It is becoming more common for individuals with digital cameras to send images of specimens by email. This can greatly speed the process of determining the type of specimen and the appropriate control measures if needed.


    The following guidelines are designed to help you make decisions about imaging insects, related arthropods and the damage they cause.

    a) Whenever possible, lay a simple ruler or a common item such as a penny next to the specimen so the relative size of the insect can be determined.

    b) When possible, take an image of damage or nests.  Photograph damage where it interfaces with "normal" plant tissue, lumber, food products, etc.

    c) Use a contrasting background color to the specimen. If in doubt, default to a light gray background.

    d) Use an intensity of light that best depicts the accurate color of the specimen.

    e) When many pests are present, take an image of several specimens in one frame.

    f) Attempt to select the best-preserved specimen to provide a close-up image of the entire top, bottom and head.  When imaging the head, try to get the base of the antennae, eyes and mouth in focus.  For specimens flattened side-to-side, such as fleas, a side view will be needed.

    How to prepare specimens for shipment

    a) Insect and Related Arthropod Samples: Put specimen(s) inside a small crush-proof container, then into a sturdy box or strong envelope with padding or packing material.  Do not use regular flat letter envelopes, as the sample will be damaged going through the postage machines. Collect and send 1 or more whole individuals.  Crushed specimens can sometimes be identified, but often only to insect family, not the species.  If the insects are abundant, send 5 to 10 of the same kind of insect, if possible.  If more than one life stage is found (adults and larvae), send both. If insects are alive, please put in a container and place in the freezer overnight to kill them before shipping.

    b) Tiny Specimens: If possible, collect in a small container rather than on sticky tape or a sticky trap.  If tape or sticky trap was used, then please attach it to another surface, sticky side down: attach loosely to a white index card or piece of white paper, or a piece of waxed paper.  Please do NOT fold sticky traps or tape with the sticky sides together.  A small piece of damp paper towel can be used to pick up tiny specimens, and then place the towel inside a sealed bag or tightly-closing small container — this is better than using tape.

    c) Dead, hard-bodied insects: such as beetles, wasps, flies, moths, and butterflies should be placed in layers of tissue paper and packaged in a small crush-proof container.

    d) Soft bodied insects and others: (Aphids, spiders, mites, grubs, and caterpillars) will break down quickly, so these should be prepared and mailed as quickly as possible, after killing them by freezing overnight with a bit of tissue or paper towel in the container to absorb moisture when they thaw.

    e) Large soft bodied insects: such as grubs or caterpillars require preparation to prevent discoloration: drop into gently boiling water for about 30 seconds, then wrap in tissue paper and put into a small crush-proof container. Please indicate original color of specimen in the submission form. It is best not to ship liquids, but if the specimen is already in liquid, please drain off as much as possible, put in a tightly-capped container, wrap the container in enough paper towels or other material to absorb all the liquid in case of breakage, then put that inside a sealed plastic bag, and use plenty of packing material and put in a crush-proof box. Please include a note saying what the liquid was.

    f) Plant Pests: Collect a progression of symptoms and pests, if available. Include or identify the plant material on which the insects were found — this is useful and sometimes necessary for pest identification. For plant material — collect a fresh sample, wrap it in several paper towels, and then in a plastic bag with a few holes. For small plants, you may want to ship the entire plant (this will NOT be returned): put a plastic bag over the pot and wrap the open end tightly around the base of the stem, so soil will not scatter inside the package.


    How to fill out submission form:

    Provide complete collection data on the form, or a piece of paper: when collected, where, and by whom, with additional location information if the sample was from someplace other than the address given for the contact person.  Please include an email address if possible, for receiving the diagnosis.


    Send by Mail:

    Include payment, the Submission Form, and the specimens (in a crush-proof container). Please ensure that your address and contact telephone number are clearly visible on the padded envelope (or other suitable packaging) when sending specimens for identification. Please submit specimens in crushproof, nonmetallic containers with securely sealed lids. Please note that large samples such as vacuum bag contents will be returned unchecked. Small samples of vacuum bag contents or contaminated produce can be inspected and must not exceed the 30ml volume of a screw-top sample tube.

    Please ensure the specimen is dead before posting. Failure to carry out these simple precautions may result in a delay before the package is opened and dealt with.

    Make sure to put enough postage. DO NOT send by any method that requires a signature — that can add a delay of 1 or more days, since if no one is in the Office at the time of delivery the package gets returned to the Post Office or sometimes even back to the sender. Send mail to following address:

    Lago Cuitzeo 180,Col. Anáhuac, C.P. 11320, Ciudad de México, México
