🚨 New World Screwworm Important Information 🚨
New World Screwworm is a serious parasite whose larvae feed on living tissue, affecting livestock, pets, wildlife, and, in rare cases, people.
Pet owners should be especially vigilant. If you notice a suspicious wound. Early detection and treatment are critical.
For dogs and cats, there is some good news: products such as Bravecto or Credelio may help protect against New World Screwworm infestations. Pet owners should continue to monitor for wounds and seek veterinary care if concerns arise.
While we currently carry one of the recommended products to treat NWS, (Credilio) we are in the process of switching over our combo(heartworm & flea) product to Credilio Quattro from Trifexis in order to protect our patients.
