In November 2018, a class-action lawsuit
was filed against Sentry for allegedly falsely advertising a flea and tick repellent called Sentry Natural Defense as being safe to use around pets when, according to plaintiffs, the repellent contains essential oils that are toxic to pets and may cause serious complications, including skin irritation, vomiting, muscle tremors, organ failure, and death. In addition, the complaint alleges that the company deceptively markets that the repellent is “Veterinarian Tested” when the repellent is actually not recommended by veterinarians. (Johnson et al v. Sergeant’s Pet Care Products, Inc. d/b/a Sentry
, Case No. 18-cv-2426, C. D. CA.)
