s are roosting (in the dark). Look at the tissue and if there are Red Mite heading back from their feed, they will be squashed on the kitchen roll as streaks of blood.
Getting rid of Red Mite
It is very hard to get rid of them completely so it is often better to get the numbers down and then find a way of keeping them down that doesn’t involve you spending hours on cleaning the house out. There are lots of different treatments that people use, some more effective than others but I will focus on what I do and have found to be the most successful for me.
If you haven’t got red mite and the weather is warm enough for them (May to October in the UK) then skip step 1 and go straight to step 2. Preventative Measures.
1. Getting rid of an infestation.
If you find lots of red mite in the coop, it’s time for a big clean up that will take a couple of hours initially, then an hour every 5 to 7 days for at least 2 more weeks.
The products I have found to work the best (that are relatively safe) are Poultry Shield and Diatom. These two are not ‘knock down’ products as such, they do take a little while to work but are none the less very effective. I also use Red Mite Powder on the hens themselves to help them through the night when the Mites are active.
Here is what I do with the Poultry Shield.
- Remove all birds from the house.
- Strip the house down as much as possible.
- Clean the house out – be careful where the bedding is going as red mite live for 6 months without a feed and will find a new home If they can. Ideally seal the bedding in bin bags or burn.
- Mix up as many watering cans of poultry shield mixture as is needed, as per the instructions on the label 1 part to 9 parts water.
- ‘Water’ all cracks in the chicken house, concentrating where there are perch ends and concentrations of red mite.
- Leave to soak for 15 minutes
- Red mites will be coming out. Cover them and the cracks with poultry shield again.
- Wait 15 minutes
- Hose out the house, concentrating on getting the pressure jet into the cracks and so on.
- Leave the house to dry.
Poultry Shield is a mild detergent and ‘washes’ the waxy coat off the red mites. It is also good for removing organic matter from the hen house so is useful for cleaning. I wouldn’t be without this!
After using the Poultry Shield, when the house is dry, I use Diatom. Diatom is made of micro skeletons of fossilised remains of diatoms. These were once a kind of algae found in water. They are microscopically sharp and pierce the outer waxy coating of the mites which causes them to dry out and die.
The second step also double up as my ‘preventative’ measures if you haven’t yet got a bad infestation
2. Preventative Measures
- Dust the ends of the perches / nest boxes and where ever else you found concentrations of red mites when cleaning.
- Rub as much into the perches as you can. Red mite will avoid the diatom and will crawl around it if they can, so make sure they have to crawl through it to get a feed.
- Repeat every couple of days for as long as you see signs of red mite in the coop.
Repeat the whole cleaning process if there are still lots of mites in 5 to 7 days. You will find you might not need to spend as long on the washing as there won’t be as many mites.
Very Important: Make sure you repeat it before 7 days so that the mites don’t have a chance to lay more eggs. A few mites become a lot in a very short space of time!
If you have a felt roof on your chicken house and they get underneath, it is usually impossible to get rid of them without removing the felt, cleaning and re-felting. My page on Chicken Houses gives more information.
Finally, I will dust the hens down between their feathers with Red Mite Powder to give them some respite during the night when the mites are active.
