Hygienic insecticides refer to medicaments mainly used in the field of public health to control vector organisms and pests that affect people's lives. It mainly includes pesticides to control vector organisms and pests such as mosquitoes, flies, fleas, cockroaches, mites, ticks, ants, and rats. These pesticides are different from those used to protect agricultural and forestry crops and kill agricultural and forestry pests. Hygienic insecticides directly act on the environment in which humans live, and some even come into contact with people for a long time, the object of protection is people.

In addition to the requirements for agricultural and forestry pesticides, the requirements for hygienic insecticides have higher requirements:

1. It has no obvious irritating effect on skin and eyes, no sensitization effect; no genotoxicity or mutagenic effect, and no delayed neurotoxicity; therefore, most of the current sanitary insecticides are of low toxicity grade, a few are of moderate toxicity, and no high toxicity is required.

2. It can be degraded in the environment after a certain period of time, without polluting the environment;

3. The active ingredients (purity) of the preparation are more than 90%, and there is no peculiar smell. Because most pesticides are poisoned to humans due to the impurities they contain, some pesticides used both in agriculture and in hygiene, such as fenitrothion, malathion, etc., must be refined, purified, and made into The control of hygienic pests is not allowed until the high purity is basically free of impurities and no obvious irritation.

5 Types of Hygienic Insecticides

Organochlorine

Organochlorines are the first class of pesticides used for sanitary pest control. Most of these pesticides have been discontinued due to their high toxicity, high residues, and great harm to the environment and human beings.

Organophosphorus

This type of insecticide has the characteristics of broad spectrum, high efficiency, low residue, simple synthesis, and low price, and is the most widely used class of insecticides. Because acephate has a good control effect on cockroaches, its usage is increasing year by year.

Carbamates

The production and use of carbamates are second only to organophosphorus, which is used in mosquito coils and electric mosquito coils.

Pyrethroids

Pyrethroids are the most rapidly developing class of insecticides in recent years, and they are also the class with the most varieties. Its main features are (1) high insecticidal activity, higher than the general organophosphorus and carbamate insecticidal activity; (2) fast knockdown; (3) broad insecticidal spectrum; (4) low to human and animal poison. At present, most of the original drugs used as household hygienic insecticides are such insecticides.

Biological Insecticide

These insecticides are not easy to develop resistance to and do not pollute the environment.
