American Dog Tick
The American dog tick is a medium-large brown tick with pale mottled markings on its shield, most often picked up by dogs and people moving through tall grass, brush lines and trail edges. Yard structure — grass height, brush, leaf litter, wildlife pressure — drives how much tick contact happens on a property.
Profile
- Scientific name
- Dermacentor variabilis
- Identification
- Brown with whitish-gray marbling on the scutum; unfed adults are flat and oval.
- Typical size
- Unfed adults about 3/16 inch (5 mm); engorged females much larger.
- Behavior
- Waits on vegetation with front legs extended to grab a passing host, a behavior called questing.
- Habitat
- Grassy field edges, brush, trail margins and unmowed lot lines.
- Diet
- Blood of mammals, including dogs and people.
- Lifecycle
- Egg, larva, nymph, adult, with a blood meal at each active stage; activity peaks in spring and early summer.
- Why it matters
- Ticks can transmit disease. Remove attached ticks promptly with fine-tipped tweezers, pulling straight out, and contact a healthcare provider or veterinarian about symptoms or bite concerns rather than relying on a website.
- DIY considerations
- Broad yard spraying without habitat reduction gives short-lived results; mowing and edge clearing do a lot of the work.
- Professional considerations
- Service targets tick habitat zones and property edges rather than open turf, on timing tied to seasonal activity.
Signs of activity
- Ticks found on dogs after time in the yard or on trails
- Ticks on clothing after walking through tall grass
- Repeat finds along a specific brushy property edge
Prevention
- Mow regularly and keep grass short near play areas and walkways
- Clear brush and leaf litter along property edges
- Create a mulch or gravel buffer between lawn and wooded areas
- Keep pets on a veterinarian-recommended tick program and check them after outdoor time
- Reduce wildlife harborage such as brush piles and open crawl spaces
