What is the earthworm like black bug in the toilet?

It is a water earthworm, also known as red filaria, red nematode, which belongs to the aquatic oligochaetes of annelids, with bright red or flesh red and orange-yellow. They mostly live in the gutter sludge (generally in the slow-flowing black sludge) that discharges sewage or wastewater, which is dense on the surface of the sludge, fixed in the sludge at one end, and the sludge vibrates in the water at one end, and immediately retracts into the sludge when it encounters alarm.

The nematodes are not large in size, but the population is highly productive. The difference between caudal gill worms and water silk worms is that the former has tail gills, and the tail is often exposed to mud, swinging and breathing with the water, and the flutter is accelerated when hypoxia; The latter does not have caudal gills.

The nematode is sexually mature at about 2 months, hermaphroditic, allogeneic fertilization, and the egg particles are encapsulated in a sac-like vermicoon composed of a transparent glial membrane. Generally, a cocoon contains 1 4 eggs, and more than 7 eggs. During the reproductive period, each adult can excrete 2 6 vermicoons.

When the water temperature is 22 32, the incubation period is generally 10 15 days, and the life span of artificial culture is about 3 months.

Don't you put them to death yet, do you still study them???

First use the spray to kill mosquitoes, and then use dichlorvos, fire, everything!

It's disgusting enough to hear what you say!!

Regret seeing your post.

It is estimated that it is a leech, that is, a locust!

The larvae will be adsorbed into the human body, so kill it! Don't scratch with your hands!

You can kill it with concentrated salt water!

It seems that it is an aquatic animal similar to an earthworm, and it is a problem with water.

Probably!

I'm using cockroach killers, and I'm using them, even though I don't know what bugs they are.

Isn't it, don't spray pesticides yet@It's disgusting.

...Have you seen the insect master? A comic. It doesn't seem to be in this world.

I also have those places in my house that I spray with laundry detergent water and they go or die?? Not anymore anyway.

Is it a centipede???
