Red mites have been the bane of chicken keepers existence for as long as there have been chickens. The impact on chickens including itchiness and irritation, anemia, an increase in disease susceptibility, decreased feed intake (which impacts on egg shell quality), decreased egg production and even death. The financial costs of Red Mite to the commercial egg industry in Europe is said to be in excess of $400million so repeated infestations of this little insect has huge ramifications.
Current Australian treatments are mainly environmental as a first line of defence. This can be incredibly time consuming, expensive and frustrating as multiple treatments are often needed to get on top of the problem, with varying degrees of success. Alternatively, some chicken keepers have turned to the off label use of livestock parasite treatments despite the lack of information/research relating to the withholding periods of eggs and meat.
Many of us have been eagerly anticipating the arrival of Exzolt to the Australian market as it is the most effective treatment available anywhere. Exzolt has used extensively by the commercial egg industry in Europe, the UK and USA for years as a key feature of this product is NO WITHHOLDING PERIOD for eggs. For the human consumption of meat and offal, there is a withdrawal period of 14 days after the last administration of Exzolt.
After the first dose, you will see a rapid and massive decrease in mite populations in a chicken house, with demonstrated 99%+ efficacy. Red mite death can even be seen within hours of administration, and the two administrations seven days apart span two mite life cycles, thus disrupting mite population dynamics.
This item is now available in its original packaging in two sizes: 50ml and 1L (special order item).
Treating the chicken with Exzolt, rather than treating the chicken’s environment, is an innovative approach to targeting mite parasites. With simple treatment through the flock’s drinking water, Exzolt is distributed to the chickens and ready to kill mites when the parasites extract the host’s blood.
Exzolt® is normally added to the water supply. However, for small flocks it can be easier to dose your chooks individually to ensure that they are getting the correct dose and noone is missed.
Add one dose (0.05ml per kg) of Exzolt® to 1-2ml of water. You can then either syringe it (carefully) into their mouth or apply this Exzolt mixture to a small piece of bread and feed the bread to the bird.
Don’t ‘drench’ it as you would for other livestock, as it’s easy to force it into the lungs accidentally.
For small flocks
The dosage for Exzolt is calculated at 0.05ml per kilo of chicken (approx). Per one kilo of chicken, mix 0.05ml of Exzolt into 50ml-100ml of clean drinking water. This is a rough approximation of water intake of a 1kg chicken over 4-12 hours.
Repeat after 7 days.
Note - a commercial brown layer chicken is approx. 2kg in weight.
A mixed flock is estimated to be 3 x 2kg and 2 x 500g chickens = 7kg total weight.
Therefore you would mix - 0.05 x 7 = 0.35ml total Exzolt for the flock into 350ml - 700ml of clean drinking water. Leave until all the water is consumed and provide clean drinking water after all medicated water is drank.
Repeat the above treatment in 7 days.
For flocks where individual dosing is impractical or not preferred, the easiest way to administer Exzolt is to add it to the first drink of the day.
Treatment in the early spring and late summer is recommended as a minimum to keep PRM under control.
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 drinking water. The amount of water is not important but as a rough guide use an amount that the chickens will drink in four to six hours. This allows all the chickens to drink without competition.
3. Mix gently to prevent foaming (think avoiding a foamy head on a beer).
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, replenish 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.
There are different protocols for mixing and administering Exzolt for commercial flocks, please refer Exzolt Administration Guide.
The required volume of product for each treatment day is calculated from the total body weight (kg) of the entire group of chickens to be treated, using the following formula:
mL product/treatment day = Total estimated BW (kg) of chickens to be treated X 0.05 mL
Therefore 50mls of product treats 5000kg body weight (e.g., 2500 chickens of 2kg body weight each) per day of treatment administration.
As this product is a two dose treatment regime, 25mls will provide the initial and followup dose to 2500 chickens of 2kg body weight. For more information, see the Exzolt Administration Guide.
Yes, Exzolt is an expensive product. But when you want to calculate the cost of each treatment we are talking about less than 10 cents per chicken per treatment.
But please don't try to skimp on the dose that you measure for the chickens. Under-dosing can lead to red mites becoming resistant over a period of time, which we definitely don't want given that Exzolt is the most effective treatment on the worldwide market at this time!
If in doubt of your poultry weight, round the weight up. If your chicken is 600g, 700g, 800g please treat them as they weight 1kg. Exzolt has been found safe for chickens at up to FIVE TIMES more than the recommended dose. Also treating for 1kg is only 0.05ml of product across two treatments. That's a tiny amount.
Secondly, please don't skip the followup/second treatment in an effort to extend your product. Again, this will mean that the mites that survive the first round of treatment but are exposed to Exzolt will be at increased chance of developing resistance. The last thing we chicken keepers need is Super Mites that are Exzolt Resistant. So follow the recommended regime properly (two treatments, seven days apart) and over administer regarding weight (not under).
It is generally recommended that you not rely/use Exzolt as a stand alone treatment. Therefore removing infected bedding/nesting material and treating the coop and surfaces with a residual insectide should still be done. This is to slow down any potential future infestations and reduce the chance of them being problematic to the chickens should red mites return.
You can find our range of coop/run treatment products here.
Eggs - Zero days (eggs are safe to be eaten if laid immediately after treatment).
Meat & Offal - 14 days (you shouldn't eat poultry until 14 days after the last treatment).

Please note - Aussie Chook Supplies is not able to post Exzolt internationally/overseas. This is due to a combination of any/all of the following reasons -
* the ingredients contained within,
* existing International licensing agreements from the Manufacturers
* Customs Regulations around export/import of veterinary/livestock medications.
Any orders fully processed will therefore be refunded minus a 5% administration fee.

Fantastic product.
By: Kristen Mclennan on 10 April 2024We treated our flock of 10,000 birds and 2 weeks later I couldn't find a mite in the trailers. Mites have been an ongoing issue for us for years. Now over a month later, I can find the odd mite crawling on the batteries, but none in the egg collection areas or nesting boxes. I anticipate that a single treatment (2 doses) will be sufficient to get us through summer without needing to be treated again.
