Methods to quickly kill small melon bugs:

1. Raise the temperature. The temperature can be raised to about 30 degrees. Small melon bugs usually breed in large numbers when the temperature is relatively low. They are not resistant to high temperatures, so they can be killed by raising the temperature.

2. Add salt and soak in 5% salt water for several days to kill the small melon bugs.

3. Use methyl blue solution, use 2 parts per million methyl blue solution, and soak for 6 hours a day.

What is a melon bug?

The melon bug belongs to the phylum Protozoa, the class Ciliates, the family Notticidae, and the genus melon bug. It mainly parasitizes fish. The skin, fins, gills, head, mouth, eyes and other parts of the body form cysts in the shape of small white dots, which are visible to the naked eye. In severe cases, small white spots can be seen all over the fish body, so it is called white spot disease. It causes congestion in various tissues on the body surface. Fish infected with melon worms are unable to feed. In addition, secondary bacterial and viral infections can cause the death of a large number of fish. The mortality rate can reach 60% to 70%, or even the entire army is annihilated. Breeding production poses a serious threat.
