The venom of the Mexican Statue Scorpion can immediately cause pain and numbness and tingling in the affected area, but usually no swelling. Children may experience restlessness and abnormal movements of the head, neck, and eyes, while adults mainly show tachycardia, hypertension, rapid breathing, weakness, and movement disorders. Both adults and children may experience difficulty breathing and excessive salivation. The sting of the Brown-tailed Scorpion can be fatal to children under 6 years old and hypertensive patients.
1. Black belly disease
Caused by scorpions eating unclean and odorous food or drinking water. The diseased scorpion has a swollen and blackened abdomen. The prevention and control method is to isolate the diseased scorpion in time, remove leftover food, stop feeding water for a few days, pay attention to food hygiene, and strengthen management.
2. Drying disease
Caused by the lack of moisture in the scorpion nest and excessive dryness. The diseased scorpion's tail and posterior abdomen turn yellow, gradually dry up, and die. Prevention and control methods: timely supply of water and maintain a certain humidity in the scorpion nest, after a few days, it can recover.
3. Withering disease
Symptoms include a dry and dull body without luster, a flattened anterior abdomen, inability to crawl, loss of balance, retreating in fear when encountering food, and gradually dying after not eating for many days. This disease can be seen all year round and is often caused by long-term failure to change the soil, excessively dry nest soil, or excessive feeding after the scorpion is starving. Treatment can be performed by forcing the scorpion to drink the water containing 3 yeast tablets and 1 terramycin tablet, which are powdered and mixed with water, twice a day for 3-4 days.
4. Black mold disease
Also known as fungal disease or black spots. This disease often occurs in autumn due to excessively high or prolonged humidity of the nesting soil, resulting in fungal infection. The main symptoms are inability to curl the posterior abdomen, softness of the whole body, sluggish movement, loss of appetite, and small black spots on the anterior abdomen. The treatment method is to force the scorpion to drink water containing 0.25 grams of chloramphenicol powder and 400 grams of water, twice a day for 3-4 days. The original nest must be disinfected, and the soil should be replaced.
5. Numbness of the legs and blackening of the foot whiskers
This disease is common when the scorpion is bitten by ants. After being infected, the foot whiskers shrink and cannot be stretched out, losing the ability to move and not wanting to eat. When it encounters a situation where it wants to run away, it turns into random jumping and rolling actions, and the diseased foot gradually turns black and dry, leading to death. The prevention and control method is to strictly prohibit ants from entering the scorpion nest and immediately remove them if found.
6. Hemiplegia
The symptom of this disease is walking sideways or walking with one side of the limbs and the second maxilliped, crawling and rolling, with no sensation in the whole body, seeming to climb out fearlessly during the day. The cause of the disease is excessive humidity in the nest due to high temperature and excessive vapor. Therefore, attention should be paid to the humidity in the nest.
7. Scorpion lice
When scorpions are severely infested, yellow powdery parasitic mites appear on their whiskers, on both sides of the chest and abdomen, legs, and tail in small cracks. These small mites are called scorpion lice. The cause of the disease is excessive humidity in the scorpion nest.
The prevention and control method is to make the scorpion nest slightly drier: at the same time,
These scorpions, which prefer humid air and slightly warm temperatures, often frequent places where people live. Arizona bark scorpions can be found trapped in indoor sinks, bathtubs, closets, and storage rooms. They can also be seen climbing walls or clinging to ceilings. Outdoors, Arizona bark scorpions often live in cracks between wooden or brick pillars. They even live in large groups under tree bark during hibernation. Due to their preference for living in areas with plenty of moisture and humidity, such as willow and tamarisk groves, the increasing prevalence of irrigated lawns in residential areas has led to an explosive growth of Arizona bark scorpions in some areas.
Arizona bark scorpions are nocturnal and prefer to ambush small prey, such as small crickets, cockroaches, and spiders.
