Control you can feel good about

Exzolt is a safe and proven oral treatment that eliminates Northern Fowl Mites in laying hens and replacement chickens with 99.9% effectiveness.1 Unlike sprays and dusts, Exzolt is administered through drinking water, helping eliminate mites without harsh treatments around your home. While mites can’t live on people or pets, controlling them helps keep them out of your space. And with no egg withdrawal period, you can keep collecting eggs as usual.

A backyard breakthrough

With simple dosing added to your chickens’ drinking water, Exzolt starts killing mites within hours to restore flock comfort. Administered in two applications seven days apart for complete control, Exzolt kills mites when they feed on the bird, treating the problem not the environment. Now available in a 4 mL size, it makes treatment practical for your backyard flock.

Northern Fowl Mites: 
A small parasite. A big problem.

They live on your chickens
Northern Fowl Mites (Ornithonyssus sylviarum) spend their entire life cycle on your birds, feeding on their blood and reproducing rapidly.

They’re hard to spot
You may not notice mites right away, but they spread fast and affect your chickens’ wellbeing and behavior from the start.

They don’t always stay in the coop
While they can’t live on people or pets, they can still bite and cause skin irritation if they come into contact with you.

The Impact on Your Flock

Your chickens provide more than eggs. They’re part of your life, and their personalities offer daily entertainment. Northern Fowl Mites can be introduced by wild birds, rodents or new chickens, quietly affecting your flock’s comfort, behavior and egg production before you even notice.

Effects on your chickens

Mites cause irritation and stress, leading to restlessness, feather pecking and increased scratching.

Changes in egg quality

Mite infestations can lead to fewer eggs and quality changes like thin shells and spotting.

Risk to overall health

Blood loss and irritation can leave chickens vulnerable to other health issues and in severe cases, death.

The science behind Exzolt

Exzolt uses fluralaner as its active ingredient, offering a different approach to Northern Fowl Mite control. Once ingested, Exzolt:

  • Starts working quickly (within 4 hours) to kill mites
  • Absorbs into the bird’s bloodstream to reach mites when they feed
  • Provides a proven 99.9% kill rate1
  • Remains effective against mites resistant to other treatments
  • Breaks the mite life cycle with two treatments seven days apart

How to use Exzolt

Exzolt uses fluralaner as its active ingredient, offering a different approach to Northern Fowl Mite control. Once ingested, Exzolt:

  1. Estimate how much water the birds will drink in 6-24 hours. (Use the day before as a reference.)
  2. Calculate amount of Exzolt needed by determining flock total weight in pounds and multiply it by .023 millilitres (or use dosing chart).
  3. Use the included syringe to measure and add Exzolt to first drink of the day. Mix gently to prevent any excess foaming.
  4. Draw fresh water into the syringe and flush it into the mixture to add any remaining Exzolt.
  5. Refill with fresh drinking water once the treated water is gone.
  6. Repeat the process once after 7 days to break the mite life cycle and control mites that were in the egg stage during the first administration.
