CHAPTER XII.

LICE AND MITES

While we have interior fixtures of the poultry house fresh in mind let

us turn our attention briefly to the study of parasites that live on

the hen, and that are detrimental to her progress. There are quite a

few various insects that depend upon the hen for their existence, but

for our purposes we can consider them in a general class of lice and

mites, as the treatment for each class is practically the same.

Let us first consider the case of lice. These insects live upon the

body of the hen, eating the flesh, and dead skin as it peels off. They

never leave the hen, and if conditions are favorable, will lay their

eggs on her body, thus multiplying rapidly if precautions are not taken

to look after this matter. It is always well to treat a setting hen for

lice before she is placed on the nest, and then once or twice after she

has started her job, because these lice will very readily transfer from

the mother hen to the young chicks, as soon as hatched, and a great

many chicks die every year from these lice. It is a splendid idea to

grease all baby chicks, especially those hatched by natural incubation,

with blue ointment, around the head parts, and wings. The hens can also

be greased in a similar manner over the whole body.

Here is where the dust box that we discussed briefly in the previous

chapter comes in, as the birds, wallowing in the box of dust, smother

the lice, by shaking the dust into the pores of the bird’s body. A

rather recent method of combating lice on birds is now fast gaining

favor. This is the Sodium Floride treatment. This is best used only on

a mild day, however, as the birds are quite wet after their treatment

under this method. The treatment is usually given as follows: Take an

ordinary wash tub, and fill nearly full with not too cold water. For

every gallon of water in the tub, add one ounce of sodium floride,

obtainable at any drug store. Dip the hen in this solution, tail

first, being sure to have a firm grasp on her so she will not splash

the water over. Dip her in this manner about three times, so that the

solution comes up in under the feathers. This method has been found

to be very effective. In extreme cases, where the lice are very bad,

another similar treatment can be given each bird about a month later.

Other good materials to apply to the bird’s body, besides those already

mentioned, are sweet oil, vaseline, and lard.

Now we come to another pest that is a little harder to get rid of

than the body lice. The mites, which are so bothersome to most

poultry, have the peculiar habit of staying on the birds only during

the night, creeping down at daylight to some crack or crevice to hide

until darkness again forces the birds to go to roost. These mites are

even more destructive in their work than are the body lice. They are

generally found in any crack or crevice about the perches. Here they

can obscure themselves, and be very close to their prey when ready to

begin their work at night. While the lice are eating insects, the mites

are sucking insects, and suck the blood of the birds during the night.

When the mite is hungry, he is of a yellowish color. When filled up,

however, with a good meal of blood, he is red. The mite is very small,

and is similar in construction to a spider.

If a flock of chickens are believed to be suffering from mites, and

there are very few, by the way, that are not troubled with these

pests, then it would be advisable first, to whitewash the poultry

house thoroughly, not only the roosting quarters, but the walls and

other fixtures inside the house. Kerosene is quite frequently used to

spray the nests with, but has not the lasting power that some of the

coal tar products possess. Recently, wood preservatives have been used

for the purposes of ridding the poultry house of mites, and very good

results have been obtained from this method.
