This kind of bugs will crawl down from the roof at home. There are more of them when the weather is humid. I would like to know what they are and what to do. Thank you.

Millipedes are also called millipedes. They like dark and moist places. There are about 10,000 species of millipedes in the world.

The largest millipede in the world is the African giant millipede, which can be up to 38 cm long. , body diameter is 4 cm. The body is dark and shiny, and when touched, its body will twist into a spiral shape.

Millipede millipede generally harms the young roots and young seedlings, young stems and leaves of plants. It does not bite, but it releases a venom that can cause temporary blindness if it touches the eyes.

Millipedes like moisture and can easily bring bacteria. Sprinkling quicklime on the places where millipedes often hang out will dry out their humid growing environment and prevent millipedes from breeding. You can also use "triazophos" spray, but people with skin allergies are best not to use it.
