Most pet owners have never heard of New World screwworm, yet it’s one of the most destructive parasites affecting animals. Unlike typical maggots that feed on dead tissue, screwworm larvae invade and feed on living tissue. Combined with the fact that a single female fly can lay hundreds of eggs in or near a wound, a minor injury can quickly become a serious medical concern.
With confirmed New World screwworm cases in Mexico, Texas, and New Mexico, and concerns about spread to neighboring states, pet parents should know the warning signs, prevention and treatment strategies.
To help protect your pet in high-risk areas:
🪰 Check your pet daily for wounds, cuts, swelling, and skin irritations. Screwworm flies are attracted to open wounds, tick bites, ear infections, hot spots, surgical incisions, and other areas of damaged skin.
🪰 Keep all wounds clean, protected, and treated promptly. Any cut, scratch, or skin lesion should be monitored closely and never left unattended.
🪰 Know the warning signs of infestation. Watch for swelling, discharge, a foul odor, excessive licking, pain, or a wound that appears to be getting larger instead of healing. Contact your veterinarian immediately if you notice any of these signs.
🪰 Use fly-control measures and repellents consistently, especially if your pet has a wound or recent surgical site.
