At Go Green Pest Control, we stay ahead of emerging pest threats to protect your family, pets, and property. One serious concern gaining attention is the New World screwworm—a dangerous parasite that can affect animals and, in rare cases, humans.
What Are New World Screwworms?
The New World screwworm (Cochliomyia hominivorax) is a type of parasitic fly. Unlike typical flies that feed on decaying matter, screwworm larvae feed on living tissue.
Adult flies lay eggs in:
- Open wounds
- Cuts or scratches
- Animal navels (in newborn livestock)
Once the eggs hatch, the larvae burrow into the flesh, causing severe damage.
Why Are Screwworms So Dangerous?
Screwworm infestations—also known as myiasis—can become life-threatening if not treated quickly.
Key dangers include:
- Rapid tissue destruction
- Severe infections
- Painful, expanding wounds
- Risk of secondary bacterial infections
In animals, especially pets and livestock, infestations can escalate quickly and even lead to death if untreated.
Risks to Children and Families
While screwworm cases in humans are rare in Canada, the risk increases with travel or exposure to affected regions.
Children may be more vulnerable because:
- They often have minor cuts and scrapes
- They may not report wounds quickly
- Hygiene habits are still developing
If larvae infest a wound, it can become a serious medical emergency.
Eye Infections and Screwworms
One of the most alarming (though rare) complications is ocular myiasis, where larvae infest the eye.
This can lead to:
- Severe irritation and redness
- Tissue damage in and around the eye
- Vision problems or even permanent damage
Immediate medical attention is critical in these cases.
How Screwworms Spread
Screwworm flies are typically found in warmer climates, particularly in parts of:
- South America
- Central America
- The Caribbean
Strict control programs have kept them out of most of North America, but global travel and climate changes increase the risk of reintroduction.
Warning Signs of Infestation
Watch for these signs in pets or people:
- Wounds that worsen quickly
- Unusual discharge or foul odor
- Visible larvae in a wound
- Increased pain or swelling
If you notice any of these, seek medical or veterinary help immediately.
Prevention Tips for Your Home
Protecting your family and pets starts with awareness and prevention:
1. Treat Wounds Immediately
Clean and cover any cuts or scratches.
2. Maintain Pet Hygiene
Check your pets regularly for wounds or skin issues.
3. Control Fly Populations
Keep garbage sealed and eliminate breeding sites.
4. Use Screens and Barriers
Prevent flies from entering your home.
5. Be Cautious When Traveling
Take extra precautions in regions where screwworms are present.
