My family lives on the eighteenth floor, why do I see centipedes in the bathroom, how do I get in?

It is possible that you have brought something you have brought home.

The centipede is a terrestrial arthropod, and its body is composed of many body segments, each of which has a long foot, so it is a multipoped creature. Centipede, also known as Tianlong, centipede, centipede, maggot, etc., is a venomous, predatory terrestrial arthropod. There are three common centipedes: red-headed, green-headed, and black-headed.

The back of the red head is reddish-black, the belly is pale red, and the feet are pale orange-red or yellow. The green head has a blue back and feet, a pale blue belly, and is small in size, about half the length of the red-headed centipede. Black-headed centipedes have a black back and feet, a yellowish belly, and are smaller.

The red-headed centipede is the best of the above three types, with large size, high yield, docile temperament, strong adaptability and fast growth. It is generally more common in rural areas, often located in damp corners, under bricks, under rotten leaves, dilapidated and damp houses, etc., and is more common in summer. Centipedes are carnivorous animals with a wide range of diets, especially preying on a variety of insects.

The centipede has venom glands that secrete venom and can be used medicinally.

Centipedes prefer to be dark and damp Wild centipedes mostly inhabit hillsides, fields, roadsides, overgrown places, or inhabit.

Between the firewood piles and roof tiles, they often inhabit dark corners such as the corners of the kitchen walls, and under the bricks and tiles around the pig and chicken coops.

Centipede tracks are also commonly seen. If you find a nest, spray it with mosquito repellent and make sure it's all gone, but don't forget to sell it, it's worth a lot.
