Ticks aren't insects. They're arachnids, related to spiders, with eight legs and a flat oval body that balloons out once they've fed. The two species we see most around the Treasure Valley are the Rocky Mountain wood tick and the American dog tick, both brown to reddish-brown and roughly the size of a sesame seed before feeding.
Behavior
Ticks Behavior & Habits
Understanding how ticks behave helps prevent infestations
Ticks don't jump or fly. They climb to the tips of grass and brush and wait with their front legs extended (a behavior called "questing") until a host walks by. They home in on CO2, body heat, and movement. Once they latch on, they feed for several days before dropping off, and they can survive months between meals.
Dangers
Ticks Risks & Dangers
What ticks can do to your health and property
Health Risks
Ticks in Idaho can transmit Rocky Mountain spotted fever, tularemia, Colorado tick fever, and (rarely) Lyme disease. A tick attached for more than a day or two can also cause tick paralysis, especially in kids and pets. Removing a tick within 24 hours of attachment dramatically lowers your disease risk.
Property Damage
No property damage. The real cost is the hit to outdoor recreation: hikes, yard work, and walking the dog all get more anxious when ticks are active.
Warning Signs
Signs of Ticks Infestation
Look for these indicators in your home
Ticks on clothing or skin after time in the foothills or tall grass
Attached ticks on dogs or cats after walks
Loose ticks crawling on floors, rugs, or pet beds indoors
Unexplained fever or flu-like symptoms after outdoor exposure
A red, expanding rash around a bite site (call your doctor right away)
Ticks in Boise & the Treasure Valley
In the Treasure Valley, tick pressure follows the wildland edge. We get most of our tick calls from foothills neighborhoods like Harris Ranch, Warm Springs Mesa, Hidden Springs, the Boise foothills above Hyde Park, and the Eagle Foothills, plus homes outside of Star, Avimor, and rural Kuna that back up to BLM land or open range. Activity ramps up in April, peaks in May and June, and tapers by late summer. The Rocky Mountain wood tick is what you'll usually find on yourself or the dog after a hike on Hulls Gulch or the Bogus Basin road trails.
Our Solution
How We Eliminate Ticks
Professional treatment for complete elimination
We treat yard perimeters, tall grass, and the woodland or brush line with a residual barrier product that knocks ticks down on contact and keeps working for weeks. We pair that with habitat advice (short grass, no leaf litter, a gravel or mulch buffer between the lawn and the wild stuff) so the yard stops looking like prime tick real estate. For foothills homes, we usually run treatments every 4 to 6 weeks from spring through early summer.
Prevention
How to Prevent Ticks
Steps you can take to reduce the risk of infestation
1
Tuck long pants into your socks before heading into tall grass or brush2
Use an EPA-registered repellent (DEET or picaridin) on skin and clothing3
Check yourself, your kids, and your dogs within a couple hours of coming inside4
Shower within two hours of being outside. Most ticks haven't attached yet and rinse right off5
Keep grass short and rake up leaf litter, especially where the lawn meets brush6
Put a 3-foot gravel or wood-chip buffer between your lawn and any wildland edgeFAQ
Ticks Questions Answered
Common questions about identification, prevention, and treatment
How do I remove a tick safely?
Grab fine-tipped tweezers, grip the tick as close to the skin as you can, and pull straight up with steady pressure. Don't twist, don't jerk, and don't bother with matches or nail polish. Clean the bite with alcohol, wash your hands, and drop the tick in a sealed bag in case you need to ID it later if you develop a fever or rash.
Is Lyme disease a real risk in Idaho?
Lyme is rare here. The blacklegged ticks that carry it aren't common in southern Idaho, so the dominant local tick-borne diseases are Rocky Mountain spotted fever, tularemia, and Colorado tick fever. Any unexplained fever or expanding rash after a tick bite still deserves a doctor visit.
Do I need tick service if my home isn't in the foothills?
Usually not for the yard itself. The Treasure Valley homes that get real tick pressure back up to foothills, BLM land, or open fields. If you live in a midtown Boise or Meridian neighborhood, most of the ticks you see are hitchhiking in on the dog after a foothills hike. Check the dog before they come inside and you'll head off most of it.
