What's active right now

Deer-tick nymphs are tapering as lone-star seed ticks swarm where that tick is established. Late-summer risk stays meaningful in brushy, wooded areas. Where the lone star tick lives (coastal and southern areas), aggressive larval 'seed tick' swarms peak now.

Local tick habitat

Havre de Grace is 74% natural land cover (50% forest, plus open and brushy areas) across its 5.94 sq mi, home to about 15,032 people. That makes it the 10th-most wooded of the 14 towns in Harford County. Deer ticks live in wooded areas, along trail edges, and in tall grass: the more of that a town has, the more places ticks can quest.

Harford County reports about 46 Lyme cases per 100,000 people a year, in the top 14% of U.S. counties for reported Lyme disease. That county-level disease pressure, combined with Havre de Grace's local habitat, sets how high its daily score can climb when the weather and season allow.
