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

Chelsea is 12% natural land cover (15% forest, plus open and brushy areas) across its 2.22 sq mi, home to about 38,319 people. That makes it the 4th-most wooded of the 4 towns in Suffolk 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.

Suffolk County reports about 23 Lyme cases per 100,000 people a year, in the top 15% of U.S. counties for reported Lyme disease. That county-level disease pressure, combined with Chelsea's local habitat, sets how high its daily score can climb when the weather and season allow.

Tick control in Chelsea, MA

Do I need tick control in Chelsea?

Today's risk in Chelsea is low (17/100), 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 Chelsea 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 Chelsea?

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.
