Embodiment 1

[0018] Before calcium cyanamide was added, there were about 230 maggots in each cesspit in the dry toilet. After 0.25kg of calcium cyanamide was put into each cesspit, after 24 hours, it was found that the live maggots were only 48, the mortality rate was 79.1%. After 48 hours, it was found that the live maggots were 0, the mortality rate was 100%, and the amount of flies and the smell on the surface of the cesspit were significantly reduced.

Embodiment 2

[0020] Add 0.25kg of calcium cyanamide and 0.25kg of calcium oxide to 100kg of livestock manure containing maggots, stir evenly, and place it for about 120 hours. No live maggots were found in the test, and the odor of livestock manure was significantly reduced.

Embodiment 3-10

[0022] On the basis of embodiment 1, change the consumption of calcium cyanamide, its situation of killing maggots is as follows:

Abstract

The invention relates to a pesticide, particularly relates to using calcium cyanamide or calcium cyanamide and calcium oxide for vanishing maggots. The invention can be used to treat feces of human and animal with harmless treatment, the breeding flies are blocked from the sources, the invention can vanish the flies well, reduce the damage of flies which is one of the four pests to human without environmental pollution, increase the fertilizer efficiency of animal and human excreta, while the calcium cyanamide is decomposed completely in the water without residues. After calcium cyanamide is decomposed, the outcome does not pollute the environment. When the animal and human excreta containing the mixture of calcium cyanamide or calcium cyanamide and calcium oxide is used as fertilizer, the fertilizer efficiency and nitrogen content are improved efficiently, so while killing maggots with calcium cyanamide, the nitrogen content is increased, the product is economical and environmental friendly, and has good economical effect.

Description

technical field [0001] The invention relates to an insecticide, in particular calcium cyanamide or calcium cyanamide and calcium oxide is used for killing maggots. Background technique [0002] As one of the "four pests", flies have always been the object of people's efforts to eliminate them. "Maggots" are the larvae of flies. Flies like to eat rotten and smelly dirty things. Generally, the food they have crawled over or bitten by can contaminate germs and viruses, and humans and animals are prone to get sick if they eat them. It mainly spreads dozens of zoonotic diseases such as cholera, dysentery, hepatitis and tuberculosis, and can also spread zoonotic parasitic diseases such as roundworm and lungfilaria, which is very harmful. The key measure to eliminate flies is to eliminate the larvae of flies. The common method is to use 1% trichlorfon solution, spray regularly or adopt the method of heat killing, which is to cover the very hot hot chaff ash on the livestock manure...
