WDCO assessment prep

Good photos help a WDCO assessment, but only when they are taken safely.

For a Maryland wildlife damage control phone or email assessment, the most useful photos are usually not close-ups of the animal. They are safe, contextual photos that show where activity is happening, how the structure or site is arranged, and what damage or entry clues are visible.

Do not enter attics, crawlspaces, roofs, chimneys, confined spaces, active dens, or unsafe areas for a photo. Do not approach bats, snakes, injured wildlife, cornered animals, or animals involved in bite, scratch, saliva, or exposure concerns.

Safe context beats risky close-ups. Photos should help explain the site, not put anyone closer to wildlife.

Maryland WDCO license scope

Maryland DNR Wildlife & Heritage Service WDCO license no. 58150 - Michael W. Deem, d/b/a Maryland Wilderness Company. Authorized license species: Birds, mammals including bats, reptiles, and amphibians.

Best evidence

Photos that usually help

Wide context

Show the whole side of the structure.

Step back and photograph the wall, roofline, deck, porch, shed, pond edge, coop, garden, or yard area where the activity is happening.

Possible entry

Show gaps and openings safely.

Photograph vents, soffits, fascia, chimney caps, foundation gaps, crawlspace openings, deck edges, shed gaps, or burrow mouths from a safe position.

Damage pattern

Show what changed.

Useful damage photos may include chewed material, torn insulation, displaced soil, disturbed mulch, gnaw marks, stained areas, damaged screens, or pond/culvert impacts.

Scale

Include safe scale when possible.

A ruler, coin, gloved hand at a safe distance, or a familiar object near droppings, tracks, holes, or damage can help interpret size without touching evidence.

Timing notes

Add the when, not just the image.

Write down time of day, sounds, odor, repeated routes, whether young animals may be present, and how long the issue has been happening.

Site pattern

Show food, water, shelter, and access.

Pet food, bird seed, trash, fruit trees, compost, ponds, poultry, crawlspaces, sheds, dense cover, and water edges can matter as much as the entry hole.

Photos to avoid

  1. Do not take close-up photos of bats, snakes, injured animals, cornered animals, or animals in living spaces if doing so puts anyone closer.
  2. Do not climb ladders, roofs, trees, steep banks, barns, or unstable structures for assessment photos.
  3. Do not enter attics, crawlspaces, chimneys, sheds, confined spaces, or outbuildings when wildlife may be present.
  4. Do not handle droppings, nesting material, carcasses, contaminated insulation, or suspected rabies/vector exposure evidence for a photo.
  5. Do not delay emergency, medical, animal-control, or official-agency contact because you are trying to gather better images.

What to send with the photos

A short note often matters as much as the images. Include the county or general Maryland region, property type, where the activity is occurring, how long it has been happening, when it is most active, whether people or pets had contact, whether young animals may be present, and what has already been tried.

For commercial food-service, poultry, livestock, ponds, culverts, or rental/property-management situations, say that up front. Those contexts may require a different route than a simple residential prevention question.

Choose the right route before paying.
