Is the blue-legged centipede poisonous? I often see it in my room because it rained two days ago, but my room is often cleaned and not very humid. ...

Without detailed description and pictures, I can only guess ... if it is blue-legged, it is estimated to be an ordinary centipede with few thorns. Some of them are colored because of natural variation, but most of them have been bitten by ants or turned blue after death, which often makes people mistakenly think that they have killed any rare species. ...

If the home is dry and clean enough, centipede will not come to the door often in theory, so it is better to carefully find the way in and out and block it properly.

The chemical control of centipede is not very effective, and sometimes it is more harmful to people than centipede. If you are in a hurry, buy a beautiful rooster as a pet, although keeping mice against centipedes is also very effective. ......

As for toxicity, it is lower in centipede. If you bite your hand, it will cause pain in your whole arm (similar to that caused by strenuous exercise, but more intense than strenuous exercise), but unless you are allergic, you don't need any treatment. Usually the pain lasts for half an hour to an hour, and it will completely return to normal the next day.

Add: You can also go to the pet store and ask if there is any skink. Skil fish is a big lizard, usually beautiful, blue or green. Although many lizards can't beat centipedes, skinks have a high winning rate and keep them clean.
