7-day outlook
Risk recalculates daily from the local forecast.
What's active right now
Lone-star larval 'seed ticks' are swarming, often dropping dozens of bites in one pass through brush. This is the stretch locals most associate with tick misery: seed-tick swarms in tall grass and brush piles. Adult and nymphal lone-star ticks stay active alongside them.
Local tick habitat
Herndon is 65% natural land cover (56% forest, plus open and brushy areas) across its 4.29 sq mi, home to about 24,935 people. That makes it the 57th-most wooded of the 69 towns in Fairfax County. Lone-star and Gulf Coast ticks favor brushy edges, overgrown fields, and open pine woods as much as deep forest: the more of that a town has, the more places ticks can quest.
Fairfax County reports about 12 Lyme cases per 100,000 people a year, in the top 19% of U.S. counties for reported Lyme disease. Lyme is a smaller factor here than in the Northeast, but lone-star tick bites (alpha-gal syndrome, ehrlichiosis) drive most local risk, and that combined pressure sets how high Herndon's daily score can climb when the weather and season allow.
Tick control in Herndon, VA
Do I need tick control in Herndon?
Today's risk in Herndon is low (33/100), so there is no urgency. Quiet stretches are actually a good time to book: pros apply barrier treatments before activity climbs, and spring nymph season is when most Lyme transmission happens.
Professional tick control in Herndon typically means a barrier treatment along the lawn edge, leaf litter, stone walls, and shady borders where ticks wait for a host, applied two to four times a season by a licensed pest control company. It is the single most effective way to cut tick numbers in the part of the yard your family actually uses.
How much does tick control cost in Herndon?
Most homeowners pay about $100 to $200 per visit for professional tick spraying, or roughly $350 to $600 for a full season of barrier treatments, depending on lot size and how wooded the property is. Quotes are free, so it costs nothing to get a real number for your yard.

Does Herndon have lone star ticks that cause alpha-gal syndrome?
Yes. The lone star tick is established in Fairfax County and is the tick most responsible for human bites in Virginia. Its bite can trigger alpha-gal syndrome, a delayed allergy to red meat and other mammal products, along with ehrlichiosis and STARI. Unlike the Northeast, Lyme disease is a minor factor here: the lone star tick, not the deer tick, is what actually drives local risk. Learn the symptoms and what foods to avoid.
