Poultry Red Mites 

To purchase Exzolt click here

The poultry red mite (Dermanyssus gallinae) is nocturnal, ie: comes out at night, is a blood-sucking parasite that can greatly impact your chickens’ welfare and egg production. Tackling the issue of poultry red mites (PRM) in backyard flocks has been challenging in the past, but Exzolt’s breakthrough treatment approach makes it easy. Simply add Exzolt (fluralaner) to your flock’s water supply twice, seven days apart, for fast and effective poultry red-mite control.

Exzolt to teat red mites in poultry

Even with a smaller-sized flock, it’s important to consider the harmful effects of poultry red mites. Chicken red mites can cause chickens stress and can have an impact on egg production and welfare. Red mite of poultry has also been commonly cited as a cause of death in hens. Therefore, hen roost mite populations must be controlled .

Using Exzolt to treat backyard poultry red mite infections. 

Treating the chicken with Exzolt, rather than treating the chicken’s environment, is an innovative approach to targeting mite parasites. With a simple cost-effective oral dosing of Exzolt, or with simple treatment through the flock’s drinking water, Exzolt is distributed to the chickens and ready to kill red mites when the parasites extract the host’s blood. Exzolt is also safe for egg layers.



The benefits of using Exzolt to treat poultry roost mites.

Exzolt causes a rapid and massive decrease in mite populations in a chicken house, with demonstrated 99%+ efficacy

Results from Exzolt treatments start within hours of administration, and the two administrations seven days apart span two mite life cycles, thus disrupting mite population dynamics

Convenient treatment of fluralaner in the drinking of the water at a low dose of 0.5 mg/kg BW per treatment day, repeated seven days later

Ready-to-use solution (1% fluralaner, 10 mg/mL) for simple dilution in drinking water and easy to measure and mix

Effective control against active, blood sucking PRM for at least two weeks following administration. (Follow standard biosecurity measures to prevent mite re-infestation. Wild birds or newly purchased chickens can re-introduce mites two weeks after treatment)

Zero egg withdrawal period.

Highly active against mite strains resistant to classical acaricides -

Well tolerated for use in layer hens, pullets and breeders, with a wide margin of safety


A recent study1 showed that PRM severely impacts hen welfare, inducing chronic stress as shown by high corticosterone (stress hormone) levels in blood and feather samples. Following treatment with Exzolt, the drop in mite count was also associated with a significant improvement of stress-induced behaviours. This happens not only at night when the mites are the most active, but also during the day.


Using Exzolt to teat red mites on hens. 

Exzolt offers fast and effective mite control in a solution that is easy to mix and administer.

1. The easiest way to administer Exzolt is to add it to the first drink of the day.

2. Add the prescribed dose of Exzolt to clean the drinking water. The amount of water is not important, but as a rough guide, use the amount that the chickens will drink in four to six hours. This allows all the chickens to drink without competition.


Add 0.5 ml / litre of drinking water in winter and 0.3 ml per litre drinking water in summer.


3. Mix gently to prevent foaming.

4. Wash out the Exzolt container with water twice to remove any traces of Exzolt and to ensure chickens get the full dose.

5. Remove all other drinking sources. Keeping the chickens in the coop or run at this stage might be helpful.

6. Once all the water and Exzolt has been consumed, it is replenished with normal drinking water. Other water sources can be replaced, and chickens let out as normal.

7. Repeat the treatment once in seven days. The second treatment is essential to ensure the efficacy of Exzolt.

Treatment in the early spring and late summer is recommended as a minimum to keep poultry red mite under control.
