The mold and mildews are there from the discovery of the earth as a planet. Mold, infestation is from the fungi family. It is generally an air borne allergic tiny particles and reproduces through the air. Mainly the toxic mold and mildews are found in damp and wet areas, food and even on the wood surfaces. The mold kingdom includes the yeast, mushrooms and the mold itself. Mildew is a kind of mold white in color.

Molds are ubiquitous like most other fungi as well as saprophytic that means these get the food from the dead and decaying surface of others. Some of them are parasitic that means they derive their food from the living things or organisms. Indoor environment is the constant source of food for the fungus like molds. The damp and humid condition is extending to provide the mold with the food. Molds are on the verge to extract their food from the house- hold articles like wallpapers, dry wall, adhesives, food, paint, paper works, some carpets, fabrics and other organic materials.

Molds are microscopic and until a large enough mass has accumulated they can only be seen with the aid of a microscope. Because they are so small, even a very thin film of dust and debris will yield an abundance of food.

Molds cannot grow without moisture. First, moisture is required in order for the mold spore (the reproductive seed-like structure of many molds) to germinate. After germination the mold's hyphae (or root like structures) secrete digestive enzymes that break down organic material. Moisture is necessary for the enzymes to be effective. Then the hyphae absorb the nutrients by "bathing" in the digested mixture. Basement mold cleaningrequires removing moisture is the most effective method for halting growth.

Allergies are the most common form that is caused by indoor molds. Stachybotrys is recognized as the black mold. About the Stachybotrys it of said Stachybotrys grows well on extremely wet building materials containing cellulose that have remained wet for more than a week. It produces mycotoxins that can irritate skin and mucous membranes. One potent mycotoxin produced by Stachybotrys is called satratoxin; it is also toxic when inhaled. Extreme care should be taken when this organism is amplified indoors. Black molds are also play an important part in irritation of human being like respiratory problem, running nose, watery eyes, burning nose and red and itchy skin. Fungi are considered as the irritants of these diseases.

A proliferation of mold and mildew can be the hall mark of hot and humid summer. The humidifier and the home air purifier for indoor would be of immense help to drive away molds.
