There are a lot of chemicals which help to kill termites. Some of them are safe for people and nature, other products can be dangerous.

In the past several dangerous products were used against termites. Unfortunately, they were dangerous not only for termites but also for people and nature.

One of these, so-called dangerous products, is called chlordane. We are going to share all the useful information about this insecticide.

Nowadays people are trying to use safer insecticides, testing the products and making researches.

What is chlordane?

Photo 2Actually chlordane is a mixture of more than 50 different chemicals.

Different variation of this product have different toxicity. It may resemble amber liquid.

The smell also differs, chlordane may have no scent or even a terrible odor.

Nowadays chlordane for termite control is not used. But some time ago it was really popular.

People used it from 1948 to 1988 to control the number of termites in the house. Everybody could buy it those times.

Chlordane was liked by homeowners and considered to be an effective insecticide. It was used not only against termites, but also other insects. The usage could differ depending what insect you are facing. Sometimes you need to mix chlordane powder with some water.

The liquid you finally get was also used for citrus crops and corn protection.

Once the chlordane was removed to the manufacturer. It happened in 1988. Why? It was discovered that this chemical is dangerous both for people and for environment.

After that lots of people refused to use it and chlordane was sent back to the company, which produced it. According to some reports chlordane was dangerous for human health.

Here you can learn more information about another effective termite control remedies: Bora-Care, Boric acid, Borate, Fipronil, Chlorpyrifos, Borax, Timbor, Termidor and Terminator.

Why was chlordane banned?

During the period while people could use this chemical, it was appreciated for its effectiveness and low price. People were really fond of its long-lasting effect. Chlordane could save a house from termites for about 20 years.

In 1988 the EPA forbid to use it as a termite control method. Now chlordane can be used only by experts against some species of ants.

The EPA proved that this chemical is a carcinogen for humans. There were a number of researches. For example, animals in laboratory got a liver cancer after they consumed a lot of chlordane. So, it may cause human cancer as well.

Also, it takes a long time for chlordane to break down in soil, usually about 25-35 years.

The termiticides used today are much safer for nature. A proper termite treatment now allows you to forget about termites for 5 years. Of course, they can’t compare with chlordane in duration, but they are safe for people, nature, animals and plants.

At the same time two more insecticides, aldrin and dieldrin, were also banned.

At those times the choice of insecticides wasn’t rich.

After the ban of three products people could only use chlorpyrifos, which was sold under the trade name Dursban. This chemical wasn’t so effective as chlordane.

Chlordane is able to create a chemical barrier between the home and the soil. And lots of people thought it was the best method, not paying attention that it can be very dangerous.

Chlordane in the environment

Though chlordane was banned in the USA long ago, it can be still used in other countries. And people should know, why it is so dangerous and what happens when it enters the environment.

The product could be used as a pesticide on gardens, lawns and crops, and in houses for termite control. In soil chlordane strongly attaches to the particles in upper layers. It doesn’t usually get to groundwater. The breakdown in soils is extremely slow, depending on the soil type.

This chemical is able to travel for long distances and can be found in water and land. Chlordane accumulates in mammals, fish and birds. It stays in environment for a very long time and can be found in food, air, soil and water.

According to the researchers from all over the world, chlordane is found in a great number of substances. It is interesting, that in Africa it was found in breast milk, in China – in water. That’s really dangerous.

Scientists also found out that chlordane still pollutes soles of America. It is depressing that chlordane was even found in soils of Yosemite National Park.
