Our natural-first approach to cluster flies in the Merrimack Valley

Exclusion before fall migration prevents entry. We seal attic access points and apply botanical barriers to deter clustering. Light traps reduce indoor populations over winter. We identify conditions common to suburban developments and customize every treatment to your property's specific needs.

Cluster Flies questions from Merrimack Valley residents

Cluster flies enter attics and wall voids in fall to overwinter. They emerge on warm days and are attracted to light. They're not breeding inside—they're parasites of earthworms.

Late summer exclusion work seals entry points before migration. Treating exterior walls with botanical repellents deters landing and entry. Prevention is far easier than removal.

Cluster flies don't bite, spread disease, or damage property. They're simply a nuisance when they emerge indoors on warm winter days. They don't breed inside homes.

Cluster flies seek protected spaces to overwinter. Attics, wall voids, and unused rooms provide shelter. They enter through gaps in soffits, vents, and around windows.
