A simmering front yard dispute on a Mankato block has turned into a courtroom fight. Minnesota Attorney General Keith Ellison filed a lawsuit Thursday against a West Lewis Street couple after neighbors reported the pair were leaving rat poison on their front lawn to keep dogs away, and at least one pet reportedly swallowed a bait block and needed emergency care. Court filings ask a judge to order that the bait be removed and to allow state inspectors to examine the property. A temporary restraining order issued by the court now bars the residents from placing rodenticide where children, pets or wildlife could reach it.

What the lawsuit says

As reported by KEYC, neighbors on the 100 block of West Lewis Street said a dog swallowed a bait block on June 26 and the owners induced vomiting, and another dog later required emergency veterinary care. Fox 9 reports the attorney general's complaint alleges the residents left bait blocks beside a sidewalk and posted signs aimed at passing dogs.

State and federal rules

Minnesota administrative rules explicitly say, "Rodent bait must be contained in a covered, tamper-resistant bait station," language the attorney general's office cites in asking the court to step in, according to the state revisor's office. Federal EPA guidance and product labels likewise restrict outdoor, above-ground use of bait blocks to tamper-resistant stations to limit access by children, pets and non-target wildlife, and those requirements form the regulatory backbone of the enforcement case.

Court action and penalties

The lawsuit asks the court to impose a civil penalty of $7,500 for each day of the alleged violation, and a judge granted a temporary restraining order this week requiring the residents to remove the bait and allow a Department of Agriculture investigator to inspect the property, according to CBS Minnesota. The order is intended to prevent further harm while state authorities pursue enforcement.

Neighbors and vets react

Neighbors told local outlets they are alarmed for both pets and children, and a Mankato dog groomer posted a warning on Facebook after the initial incident, per Southern Minnesota News. Veterinarians at the Minnesota Valley Pet Hospital noted that common signs of rodenticide exposure include unusual bleeding, bruising, weakness and loss of appetite, and they urged owners to contact a veterinarian or the Minnesota Pet Poison Hotline instead of trying at-home treatments.

What happens next

The temporary restraining order will remain in effect while the Department of Agriculture conducts its inspection and the attorney general's office pursues civil enforcement under state pesticide rules, the filings indicate and local outlets report. Pet owners in the neighborhood are being urged to supervise animals closely and to seek veterinary care immediately if they suspect exposure.
