🚨 New World Screwworm 🚨
Protect your animals and community—NWS was confirmed in Cochise County, Arizona 10/28/26!
This dangerous fly lays eggs in open wounds of animals (and sometimes people). Within just 12-24 hours, the eggs hatch into maggots that feed on living tissue, causing severe pain. After 3-7 days, the larvae drop to the ground and new flies emerge—repeating the cycle.
Check your animals regularly for:
• Wounds that won’t heal or get worse
• Visible maggots/larvae
• Licking, biting, or scratching at wounds
• Swelling, discharge, or foul odor
• Restlessness, isolation, or odd behavior
If you spot any of these signs in livestock, pets, strays, or wildlife, act fast!
📞 Call the Navajo Veterinary Program at (505) 397-5355 for guidance, testing, and treatment.
