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

South Run is 95% natural land cover (90% forest, plus open and brushy areas) across its 2.53 sq mi, home to about 6,462 people. That makes it the 7th-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 South Run's daily score can climb when the weather and season allow.

Tick control in South Run, VA

Do I need tick control in South Run?

Tick activity in South Run is moderate today (35/100). Ticks are out, especially along yard edges, leaf litter, and shady borders. A seasonal treatment plan keeps numbers down before peak weeks hit.

Professional tick control in South Run 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 South Run?

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 South Run 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.
