What Are Ticks and How to Use Medication to Exterminate Tick Larvae on Dogs and Cattle at Home

In recent years, news of tick bites has been common, so what exactly are ticks? How do you kill tick larvae clean on your home, dogs, and cattle? What medication can exterminate them? Ticks (p) are also called wall ticks, turtle bites, commonly known as dog ticks, grass ticks, cattle ticks, grass ticks, dog beans, cattle ticks. In Sichuan dialect, they are called bi sha (pronounced shà), etc. They lie dormant in the grass and plants of low hills, or lodge in the fur of livestock and other animals. When not engorged with blood, the small ones are only as big as a shriveled mung bean, and some are as fine as a grain of rice; after engorging with blood, they are as big as a plump soybean, and the large ones can reach the size of a fingernail. The anaplasmosis transmitted by tick bites is an infectious disease, and humans are generally susceptible to it. Medical staff or their caregivers who have close contact with critically ill patients or directly contact patients' blood and other body fluids may also become infected if they do not pay attention to protection.

I. Tick Classification

1. By morphological characteristics

1) Hard ticks

The body is oval; when not engorged with blood, the abdomen and back are flat, with the back slightly raised; adult body length is 2-10mm; after engorging with blood, it swells up like a red bean or castor bean, and the large ones can reach 30mm in length.

2) Soft ticks

The capitulum is on the ventral side of the body and cannot be seen from the dorsal side; there is no porose area on the dorsal surface of the basis capituli. The dorsal surface of the body has no scutum; the body surface is mostly granular small tubercles, or has wrinkles and disc-shaped depressions.

2. Main species

1) Ixodes persulcatus: the scutum is brown, the palps are slender and cylindrical, and the auricular processes of the basis capituli are bluntly toothed.

2) Dermacentor nuttalli: the scutum has enamel-like spots, with eyes and festoons; the palps are wide and short, the basis capituli is rectangular, and the dorsal spur of tarsus I is short and blunt.

3) Hyalomma asiaticum kozlovi: the scutum is reddish brown, with eyes and festoons; the palps are long and cylindrical, and the second segment is notably elongated; the legs are pale yellow, with obvious pale rings at each joint; the cervical grooves of the male are obvious and deep-grooved, and the spiracular plate is pipe-shaped.

4) Ornithodoros papillipes: the body surface is granular, and the intersection of the postanal transverse groove and the postanal median groove is almost a right angle.

II. How to prevent tick bites?

1. To eliminate ticks on the body surface of livestock and in livestock sheds, insecticides such as trichlorfon and dichlorvos can be sprayed. Housing should be ventilated and dry; fill and plaster wall cracks, seal caves, and clean livestock and poultry sheds thoroughly or spray them with medication to eliminate tick breeding sites.

2. Strengthen personal protection. When entering forest areas or working in the field, wear long-sleeved clothing, tighten the belt, cuffs, and trouser legs, tie a towel around the neck, and apply ointment to the skin surface to prevent tick bites. Take a bath and change clothes after returning from outings to prevent bringing ticks home.

In addition, it is summer now, which is a good season for people to travel. Here I want to remind everyone that when playing in the wild, in addition to the above two points to note, do not go to scenic areas that have not yet been well developed, and try to go less to forests and wild places with dense grass. In this way, we will avoid tick bites.

III. What medication is used to kill ticks?

After a certain pesticide is used for a long time, ticks will develop resistance, so pesticides should be mixed or used in rotation.

There are mainly two ways to eliminate ticks on livestock: one is direct capture, and the other is using chemical drugs to kill ticks. When ticks are found, they should be pulled off and then killed together. When pulling, the tick body should be perpendicular to the skin, then pulled upward, to avoid the tick's false head breaking off in the skin and causing inflammation. However, this method can only be used when there are few livestock and sufficient manpower.

For eliminating ticks with chemical drugs, commonly used ones include pyrethroid insecticides, organophosphorus insecticides, amidine insecticides, etc. According to the season and application target, methods such as spraying and dipping can be selected. However, it should be noted that after these pesticides are used for a long time, ticks will develop resistance, so pesticides should be mixed or used in rotation.

In recent years, genetic control and biological control have begun to be used to kill ticks. The former uses radiation or chemical sterilants to make male ticks lose reproductive ability, causing the tick population to continuously decline; the latter uses ticks' natural enemies to kill ticks. Some parasitic wasps in the family Encyrtidae of the order Hymenoptera have now been found to lay eggs in some nymphal ticks, and the adults emerge from the nymphal ticks only after becoming adults; the nymphal ticks die shortly after parasitism. Insects in the family Reduviidae can also cause tick death.
