Common bugs at home

Fleas, about 1 mm in length, are longitudinally flat and difficult to crush. They must be trampled to death with their nails. Fleas suck blood and reproduce quickly, but modern living conditions are good, mainly spread by animals such as cats and dogs outside. Eggs are oval balls with white luster, and there will be a creaking sound when squeezed with nails.

Bedbugs, or bedbugs, are 4. 5mm long and flat.

Bedbugs suck blood. Good sanitary conditions are rare, but recently there seems to be more in the south.

Acari, about 5 mm to 1 cm, has eight legs, which is different from the six legs of ordinary insects. It will be spherical after sucking blood. Rare. In the wild, it will hide in plant weeds and take the opportunity to attach itself to animals. If you are bitten, don't pull it out, its mouthparts will break in the skin and cause infection. Another case shows that ticks can be infected with an enzyme, which makes people allergic to meat (meat can't be used to lose weight).
