Termites are warm-loving insects, and temperature is the main factor affecting the distribution of termites, so termites are distributed on both sides of the equator. The closer to the equator, the more species and density of termites, and the more complicated their lifestyles. The optimum temperature of termites is 25-30 degrees Celsius, and the lowest lethal temperature is -3 degrees Celsius.

2. Humidity requirements

Termite species with developed groups need special water supply to maintain the group's demand for water and humidity. The water content of termite insects is about 79%, and the water content of termite nests accounts for 30%-37%, with an average of 33%. Termite colony has a special water absorption line (water absorption ant channel) leading to the source, which ensures the water demand of itself and its nest through the water absorption line.

3, light requirements

Termites live in nests for a long time, so most individuals are photophobic. However, the diffusion and development of termite colony can not be separated from light environment, and winged adults all have phototaxis habits when they fly away from the colony.

Winged adults who often flock in the evening and fly away from the flock have strong phototaxis; Yellow-winged termites are carried out in the bright moonlight morning. All winged adults have well-developed monocular and compound eyes, and like many other insects, they have a strong positive reaction to light.

4. Soil requirements

Except arboreal termites have no direct relationship with soil, civil termites and soil-dwelling termites have very close relationships with soil. Soil-dwelling termites, in particular, can't survive without soil. Soil-dwelling termites have strict choices about soil. Soil is also the main component of civil termite nests and ant paths.

Matters needing attention

1, the biggest harm of termites lies in the damage to indoor objects, because they like to eat cellulose-containing substances, such as wood, cotton, wool, silk and other raw materials and their products; In addition, it can secrete formic acid, which can corrode and destroy reinforced concrete, various metal devices, various wires and cables, plastic products and so on.

2. The renovation of the house destroyed the pipe network and created a more convenient way for termites to enter the house. Dado, ceiling, lamp trough, wooden floor and wallpaper all create a dark and humid growth environment and rich food for termites, which are the most vulnerable links.

3. Try to find an ant nest or ant path where the ants are found, and spray the ant killing powder on the termites in the ant nest or ant path as much as possible, so that they can infect each other and achieve the effect of killing.
