Red louse or black louse,
the most harmful parasite of the poultry and the scourge of livestock
Did the red lice invade your chicken or your chicken? They multiply at a high speed v and you don't know what to start with? an invasion of red lice can become very complicated if you do not act quickly. Find in this folder a set of answers and products that will allow you to fight this invasive insect at best.
A ectoparasite is a parasite that lives on the body surface of a living being. there are several species of red lice whose most important is the dermanyssus gallinae.
The red louse is an arthropode of the class of arachnides, the order of the mites, the suborder of the mesostigma and the family of the dermanyssidae.
It is 0.5 to 2 mm in adulthood. its color ranges from gray to bright red, then to dark red almost black when its digestion ended. The red louse larva is white transparent.
Like the bed bug, it's very difficult to get rid of it.
Acarien ectoparasite aviaire external, temporary et noctambule, il reste caché la journée dans des crevasses ou des cracks à proximité de ses hosts et attack la nuit en leur suçant le sang (duration 1 à 2 heures).
Normally it survives only temporarily on men and mammals but people in regular contact with infested animals can develop irritations and allergies following bites.
How does the red louse spot your host to feed ?
The red lice spot their hosts with a highly specialized recognition system, known as the choir, located on the antennae. these receptors are sensitive to different parameters:
- perception of heat
- infrared radiation
- day/night vision
- Chimio-olfactory (perception of specific molecules and odours)
Specific data (osmolarity, salinity, chemical composition) confirm to the “peggers” like the red lice that they are well sucking blood and that they can therefore feed themselves. the accuracy of the sensory perception is related to the number of choirs. the red pulse that lives near its host has few antennae receptors (less than 50, compared to a mosquito or fly that can have up to 5000). They also serve the needs of sexuality.
Watch the red louse !
The red louse is a little vampire that settles in the hens as well as in the pigeonniers.
He attacks the sleeping animals at night, sucks their blood, then withdraws again.
All breeders are unanimous: the red louse is today the most harmful external parasite of the poultry, dovecots and hens.
Amateur enthusiasts, small farms or professional livestock, whether they are ornamental birds (canaris, pigeons, serins, wigs). laying hens, pheasants or cails, few are those that have not been contaminated at least once by this parasite.
The phenomenon is not only French but global, it is estimated that 70 to 80 per cent professional hens of hens are affected more or less severely. the consequences can go from the decline of the bridges to death by exhaustion of the chickens.
The red louse in general is introduced into the chicken coop, cage or aviary by an outside arrival but it can also be introduced by the breeder or mammal like rat or dog.
According to studies by the Italian (Technical Institute of Acroculture) the strains attacking wild birds would be different. It is therefore unlikely that this parasite will be brought back by a nearby nest.
His presence is a danger :
By its repeated bites, it causes anemia (decrease in the number of red blood cells) that can be fatal in young subjects. with pathogenic bacteria, it can inoculate germs (salmonella) or parasites (plasmodium) and can sometimes attack humans.
Its presence can result in decreases in the deck in the chickens (but also one discoloration of yellow and stubborn eggs) or a severe anemia in pigeons.
In favourable conditions of temperature and humidity, the complete cycle (egg egg) of the red louse does not exceed one week. It is obvious that the destruction of this parasite is not very simple, especially since it is able to stay for 8 months without feeding or survive by taking the necessary proteins in the cracks, feathers and dust !
Given its rapid reproduction (a female can lay 100 to 200 eggs per week), infestations can quickly become very important (exponential multiplication).
Like all insects that reproduce very quickly, there is potentially a risk that red lice that survive treatment, develop resistance to the insecticide used.
The red louse is a dreadful parasite, to destroy it, it will have to arm itself with courage and patience.
Main areas infested by the red louse
Red lice can hide in many places away from light but in the most classic you have:
- under the cracks on caillebotis,
- under the cuvettes of layings and fastening hooks,
- in the tubes of the perch,
- under the nest bar.
It is obvious that the total destruction of the colony is very difficult. the goal of the treatment is to maintain a population of red lice at an acceptable level so that there is no impact on the quality and quantity of the production.
If your pets get out or seem exhausted, if an unusual mortality touches your cubes or if the eggs have small red spots, then it is possible that you are also at the head of a red lice farm!
To be certain and if you have not yet had the opportunity to see it, there is a very easy and very effective way to detect their presence. as these insects search for a dark corner near their hosts, get them a hiding place: one or more pieces of white rag in ball near your pets, after a few days fold them and check the presence or absence of parasite.
When do you treat the red louse ?
Normally, the red louse does not support the light. However, it was found that when the infestation is very important (too much lice compared to the amount of hosts) it can be present permanently, light or not, on its host (the lice relaying to feed).
To destroy a maximum of red lice, it is therefore advisable to treat when the building is completely in the dark, that is 2 hours after the disappearance of light or early in the morning before the appearance of light.
Whatever the treatment product you will use, its effectiveness will depend on the quality of its application but especially on the cleanliness of the supports.
Dust, feathers, cracks, ... are ideal hiding places for red lice. The surfaces should therefore be as clean as possible.
1 - cleaning
- Empty the space completely by getting rid of the straw or litter (burning it if possible,),
- Gratify, brush, carefully remove horizontal but also vertical or high pressure cleaner or water jet ,
- Remove all the dust,
- Wash with water added to soap black,
- Dismantle the farm equipment as much as possible and clean it up.
2 - treatment of buildings
a. for the treatment of large surfaces, we recommend that you equip yourself with a sprayer type garden and of insecticide 4j concentrate. to give you an idea, the 250ml bottle diluted in 5 litres of water will allow you to treat about 50m2 (also available in 125ml, 500ml or 1 litre).
Water well all horizontal and vertical surfaces, by insisting well in the corners, cracks, slits. this treatment, if done methodically, should eliminate much of the adults and eggs.
b. when everything is dry, you can then sprinkle all horizontal surfaces, nests and kidneys, with our datum earth.
It is not necessary to use large amounts of powder, but on the other hand, it is important to distribute the product as evenly as possible, so as to block the access of the lice. in a cage or aviary if you use a newspaper, it is advisable to put the powder under and on the newspaper. the principle is that the Red louse crosses the surface treated with the powder before reaching its prey. for action in the smallest corners, small holes and interstices difficult to access, prefer thespray diatom in the form of aerosol.
c. Since the pulse cycle is one week, it may be necessary to consider treating 2 to 3 times, at one week interval, cages, cracks and all kidneys.
3 - animal treatment
After processing the buildings it will be necessary to treat your animals with our insect repellent Alt'o zinsect spray. a formula combining 3 recognized active ingredients (eucalyptus citriodora, vegetable pyrethre and géraniol), extremely effective to keep pest insects remotely. This will prevent the return of red lice to treated animals (repulsive effect) but also eliminate those already present on animals (precludes blood catch). for example, for a chicken: 6 to 8 ml (2 to 3 sprays): it will be necessary to raise the feathers during the treatment because it is often in its places that the red louse avoids. this treatment is enough for about 10 days.
4 - treatment of perch, cages, eaters.
To treat all small corners and mainly vertical surfaces, where liquids do not hold, you can use our insect repellent Alt'o zinsect gel. this product with the same composition as the alt'o zinsect spray, but it is formulated as a gel. it easily applies with a brush.
5 - remain vigilant
From time to time, think about taking the rag test and check the presence or absence of lice.
6 - be preventive :
Most liquid insecticides, whether natural or synthetic, degrade over time and quickly lose their effectiveness. products de datum earth (also called kieselguhr or silicon dioxide) remain effective as long as they are not covered with a layer of dust and are dry.
You can, at each cleaning of your aviary or chicken coop, carry out a systematic application of diatomed earth. This safe operation ( silicon dioxide is also used in animal feed) gives excellent results to protect your animals from lice.

R: We don't have a professional address that uses our products on the Paris region. I don't think these insects attack the man. the red louse is mainly a parasite of chickens and birds so also on pigeons. If you remove the pigeons, and especially the nest (slow) you will remove the red louse.

Q: What do you need to do when men were attacked by red lice of chickens ?
R: If you talk about the bites that the red louse can cause, then you need to use the same products as for the bites of other insects. We have an effective body lotion based on eucalyptus citriodora.
Q: While I was looking for bio treatment for chicken lice on google, I discovered your site. It's very interesting. Do you have experiences of this kind of treatment? I held the lavender, but how do I treat in an open shelter ?
R: The essential oil of lavender is correct. It is often used to treat lice, but children! no essential oil is really insecticide but rather repulsive. However, we have 100% natural insecticides that could suit you.
Q: I share my living room with a tribe of eight canaries. I would like you to tell me a harmless insecticide about these birds very sensitive to their environment. the danger comes especially from the mosquitoes of the smallpox on the birds.

R: The red louse is rather resistant as an insect. I'm not sure about the effectiveness of aerosols on this insect. in natural we have the bomb Ecodoo All insects. you can try the smokers, but there, it's no longer natural at all and the result is not guaranteed. for carpeting, insecticide 4j to 5% is not a problem.
Q: I let myself contact you for information on the earth of diatomy I was advised your land against the chicken lice, the summer dermite for horses and mites on horses and chickens and dog chips. that you advise me as a product and quantity ?
R: The earth of diatomy is not a miracle product that solves all problems. We often associate it with another treatment that will complete it. for red lice do not hesitate to read our file on this subject. Given the returns, it would seem that the earth of diatoma alone can not completely solve all your problems! for the lice of the chickens or insects on the horses we have the ALT'O ZINSECT Spray. there are also many products for cats, dogs, on our site.
Q: I am looking for a new product that is more effective and especially less toxic to health than I currently have against the red lice of the hens. In fact, I found brown lice on the waterbowl and white lice. So I started disinfecting with my usual product, saniterpern + pyrethra powder in the weights. all are not dead and I don't want to have a new infestation as I could have in the past by lack of knowledge. my chickens are in an old stable, quite large surface with unfortunately lots of wood. difficult to treat everything. Obviously, they have a course of about 400 m2 outside. What do you recommend to me as a product ?
R: All the answers are on this red lice page.
Q: My canaris have lice I will soon begin breeding; What is the best and effective solution to get rid of these lice ?
R: You will find all your answers on this red lice page.
Q: I have received my order with an insect sprayer, margosa extract and margosa extract ALT'O ZINSECT spray. these products to eliminate lice in my chicken. I come by this email to ask you if after the treatment (which I did yesterday) can I eat the eggs of my chickens? Indeed, on your site I have not read any contraindications about this.
R: Based on all the information we have, there is no problem in consuming eggs treated in margosa since this product is primarily intended for the treatment of crops.
Concerning the 4j insecticide, you must of course avoid watering the eggs with. If the egg membrane is well permeable in the air, it does not have it in the water. with the ALT'O ZINSECT there can be no contamination of the eggs.
To treat a hen, it will be necessary to:
- remove eggs and chickens, not by dangers for them but to do one:
- complete cleaning of the space (fientes on the ground or perch) . if you do not start with this operation, you will find it difficult to eliminate red lice.
- spray insecticide 4j.
Q: On the product page ALT'O ZINSECT, your application example concerns the treatment of a horse. how much spray should I apply on my chickens with the product ALT'O ZINSECT Spray ?
R: You are right, the proportions to treat a horse or a chicken are necessarily different. Horse is like human. its perspiration destroys most products like mosquito or solar protections, so it must be renewed more often. for a chicken, if it does not take rain treatment every 2 or 3 weeks is largely enough.
The problem of the chicken with respect to the horse: for the horse, we treat the skin. for the chicken, it is more difficult to raise the feathers a bit during the treatment: 2 or 3 spray shots / chicken is enough for 2 weeks.
Q: What particular danger is there in the use of ALT'O ZINSECT Spray ?
R: The product ALT'O ZINSECT Does not contain any phrase r (danger) so its use or overdose does not pose any danger.
Q: Hello, I am a chicken breeder, pigeons and rabbits for avicole exhibitions in alsace. Here's my concern. For a month I have chips in my chicken, and on my dog, so I also think about chickens, pigeons and rabbits. I read that pyrethre is effective as well as at home. but which choice can you advise me in choosing your range? I'm not a client yet but will become a client .
R: All mammals have their chips but the chip of the chickens or pigeons is called the red louse (the bird chip is called dasypsyllus gallinulae. the ceratophyllus gallinae is the chicken chip. the rabbit and the dog have chips.
The difference between the chip and the red lice: the chip lives on the animal while the red louse goes on the animal only at night and only to feed. Then he goes back to hide. The treatment to be performed is therefore not the same. Another thing, it's not because you have lice on your chickens that you will necessarily have lice on the pigeons. Idem for the dog and the rabbit. It is not the same species and they do not go especially on other mammals (except when it does not find to eat!!!). concerning the products to be used, you will find all your answers on our red lice page.
Q: For a week, I've been stinging myself with little beasts like red lice. It probably comes from the pigeon nest that there is currently on my balcony. I would like to treat my entire apartment with the product " concentrated 4j insecticide" that you recommend. Can you tell me if I can spray it on my mattress, clothes etc ?
R: Insecticide 4j is a contact insecticide that will act very well against the red louse. you can treat all surfaces with this product. He doesn't stain. The pyrethre deteriorates in a few hours. it can remain according to the concentration used a fat film of potassium soap contained in the formula (which allows an asphyxiating effect vis to larvae and eggs). This residue is in no way toxic and remains perfectly lesivable (it is only soap). for clothing, aerosol method Ecodoo will be more effective. Take the clothes to be treated and put them in a large garbage bag. bomb with the aerosol inside the bag, close the bag as hermetically possible. wait 24 hours and reopen the bag. wash at 60°C or the switch to the freezer can also, depending on the type of textile, give good results against the presence of this type of insect. and last thing, advice, if you can, either treat the pigeons and their nest against the red louse, or evacuate the nest and make a complete cleaning of the space.
