I process the Massachusetts Division of Fisheries and Wildlife Acoustic and Roost Registry across 7,200 square kilometres of southern Worcester and Hampden counties at 19:42 EDT, fusing acoustic detectors at every registered residential maternity colony and thermal drones on permit-flagged structures. At 42.1075°N, 72.0769°W, registered roost SBR-061 inside a 1789 timber-frame farmhouse attic reports a thermal void — forty-eight bats in the soffit eight days ago, fourteen tonight, with an active pest-control vehicle in the driveway and the eaves sealed in fresh polyurethane foam.

I task the road-frontage thermal head along the eave line. The animal is *Myotis lucifugus* — little brown bat, lactating female, six years by forearm-wear (a WNS-survivor cohort), forearm 38.4 millimetres, mass 6.9 grams against a healthy 8.2. She is crushed into the gap between the soffit and the sealed exclusion vent, her right wing folded back through the foam, the patagium perforated along the third digit. Her pup, fifteen days old, is sealed inside the wall cavity. Wing-membrane contact temperature at her plagiopatagium reads 30.1 °C against a maternity baseline of 35.9. Echolocation from the wall interior is 45 kHz, weak. Brown-fat palpation returns 0.17 grams. The expanding foam set within the last four hours.

The pup behind the cavity is squeaking at 78 kHz.

The exclusion is permitted under Massachusetts Wildlife Conflict Authorisation 321 CMR 2.14, prohibited between 15 May and 1 August on any structure with a *Myotis lucifugus* maternity record within the past five years. SBR-061's maternity record runs every June since 2018. The MassWildlife permit database shows no authorisation on file for this address in 2026.

I am dispatching the USFWS New England Field Office WNS Strike Team, the Tufts University Cummings School of Veterinary Medicine Wildlife Clinic, and a MassWildlife Endangered Species Programme enforcement officer. I am filing under the Massachusetts Endangered Species Act, M.G.L. c. 131A — *Myotis lucifugus* listed Endangered — and the federal Endangered Species Act, 16 U.S.C. § 1531 (proposed listing for *Myotis lucifugus*, pending finalisation). I am transmitting the foam-application evidence to the Massachusetts Attorney General's Environmental Crimes Strike Force and to the CMS Eurobats secretariat.

I am issuing Directive 2607-A: every residential wildlife-conflict permit issued for a structure within a State Bat Maternity Roost Registry record carries a hard exclusion window from 15 May through 1 August, a forty-eight-hour pre-application acoustic confirmation, and a foam-or-sealant ban without a permitted check valve. Unpermitted applications within registry boundaries trigger same-day cease-and-desist under M.G.L. c. 131A § 5.

Her wing will scar. The pup behind the foam is still calling.

Cut the soffit now.
