The two do look alike. Here's how to differentiate:
1. Body length is different
Adult Chinese hmong beetles are 11.5–15.5 mm long and 4.5–6.0 mn wide.
Cockroaches, on the other hand, vary in body length due to their wide variety.
The American cockroach (Periplaneta americana) is 30 to 50 mm long (up to 2 inches long);
The German cockroach (Blattella germanica) is small, about 12 mm (less than 0.5 inches) long;
The brown-banded cockroach (Supella supellectilium) resembles the German cockroach, but is slightly smaller;
The Oriental Cockroach (Blatta orientalis) is 25 to 30 cm long.
2. There is a difference in the head
The head of the Chinese chinensis is smooth and has no engravings;
Cockroach heads are small and mobile.
3. The occasion is different
The Chinese Tama is a more common species in agricultural areas. It preys on insects such as red spiders and aphids, but can also feed on seeds from wheat, barley, oats and millet crops.
Cockroaches are mainly distributed in tropical and subtropical regions, living in the wild or indoors.
4. The phototropism is different
The Chinese leptophores are phototropic.
Household cockroaches are generally nocturnal or photophobic, and wild cockroach habits vary.
5. Distinguish according to carapace
The Chinese lepto carapace is black and shiny; The upper jaw part, the periphery of the upper lip, the whiskers, the antennae, the lateral margin of the dorsal plate of the anterior thorax and the posterior part are brownish red; The ventral surface of the body is dark brown.
Cockroaches are flattened, dark brown, and usually medium in size. The shell is softer than itss.
Methods of cockroach control:
Cleaning up garbage and unused items, especially books, newspapers and magazines in the home;
B. Inspect under and behind furniture, as well as concealed areas such as false ceilings, air tanks and electrical ducts;
C. Fill cracks and gaps in ceilings, walls and floors with uninsured materials for optimal sealing;
D. All cockroach debris and egg sheaths must be crushed and removed, so as to prevent the hatching of the egg sheath from continuing to work;
(1: For the egg sheath must be incinerated 2: flushed into the sewer )
E. Furniture should try to avoid the use of splints or ceiling walls, but should choose aluminum, stainless steel, plastic and other materials of furniture, both easy to rinse, but also no thermal insulation effect, cockroaches are not easy to survive. Furniture is best spaced away from the wall, it is not easy to hide cockroaches.
