Bed bug affects the whole world. These six-legged parasites have bothered since as early as 400BC and are still haunting the millennium. After the discovery of pest control chemicals such as DDT, it is relatively easy to eradicate these creatures. Keeping your home clean can prevent other animals from entering your home, but this one's not after the trash.

Environmentally friendly pesticides are being developed to counter-act these pests, which still have some health implications.

This bug stayed cool and did not survive at temperatures higher than 32 degrees. Washing your sheets, clothes, curtains in hot water kill bed bug eggs. The bed bugs that are far in furniture can be eradicated with the use of pesticides.
Pesticides are used to combat these bugs in a controlled manner. And by controlled, I mean on that involves extreme discretion. Chemicals used to destroy these creatures are able to eradicate human, too.
There are companies that claim to do the scary-work for us so we can lay back and relax. And I believe there are more than a few to choose from. You will want to choose a qualified, have more than a decade of experience and technology conscious.
