Molds are fungi that can be found both indoors and outdoors. No one knows how many species of fungi exist but estimates range from tens of thousands to perhaps three hundred thousand or more. Molds grow best in warm, damp, and humid conditions, and spread and reproduce by making spores. Mold spores can survive harsh environmental conditions, such as dry conditions, that do not support normal mold growth.
Molds are found in virtually every environment and can be detected, both indoors and outdoors, year round. Mold growth is encouraged by warm and humid conditions. Outdoors they can be found in shady, damp areas or places where leaves or other vegetation is decomposing. Indoors they can be found where humidity levels are high, such as basements or showers.
Some people are sensitive to molds. For these people, exposure to molds can cause symptoms such as nasal stuffiness, eye irritation, wheezing, or skin irritation. Others, such as those with serious allergies to molds or those exposed to large amounts of mold in occupational settings, may have more severe reactions —including fever and shortness of breath. Some people with chronic lung illnesses, such as obstructive lung disease, may develop mold infections in their lungs.
Recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies, but more research is needed in this regard.
Mold growth, which often looks like spots, can be many different colors, and can smell musty. If you can see or smell mold, a health risk may be present. You do not need to know the type of mold growing in your home, and CDC does not recommend or perform routine sampling for molds. No matter what type of mold is present, you should remove it. Since the effect of mold on people can vary greatly, either because of the amount or type of mold, you can not rely on sampling and culturing to know your health risk. Also, good sampling for mold can be expensive, and standards for judging what is and what is not an acceptable quantity of mold have not been set. The best practice is to remove the mold and work to prevent future growth.
While the Center for Environmental Health can address mold issues from a sanitation perspective in the facilities we inspect, such as restaurants and hotels, we do not have the authority to address mold issues in other businesses, private residences, or rental properties. We do offer resources that may be able to assist you in resolving mold issues in these types of structures on our Resources for Non-EH Program Complaints page.
The best way to prevent infection from mosquito-borne diseases is to avoid getting bitten by mosquitoes. Bites can be minimized when you follow these tips:
- Wear loose-fitting and light colored long sleeved shirts, pants, and socks to reduce the amount of exposed skin.
- Cover exposed skin with an EPA-registered insect repellent containing DEET, IR3535, Oil of Lemon Eucalyptus, or Picaridin. Always follow label instructions, especially when applying insect repellant to children. Do not let children apply their own insect repellant.
- Treat clothing and gear with permethrin or purchase pre-treated items.
- Drain, fill, or get rid of item and areas the hold water, such as:
- Containers that hold water, such as buckets, wheelbarrows, tires, and kid’s toys
- Unmaintained swimming pools
- Plastic sheeting and tarps
- Clogged ditches and pipes
- Shallow edges of ponds
- Low areas, tire ruts, and puddles
- Tree holes and hollow stumps
- Leaky pipes and outdoor faucets
- Small areas of water that can’t be drained
- Make sure doors and windows are in good repair and fit tightly, and fix torn or damaged screens to keep mosquitoes out of the house.
- Trim or remove overgrown plants that provide areas for mosquitoes to rest.

Effective mosquito control can be a challenge due to vacant and unmaintained properties. The Cobb & Douglas Public Health, Center for Environmental Health is available to evaluate these properties and initiate measures to resolve mosquito harborage issues. To file a complaint, please contact our Cobb County office at 770-435-7815 or our Douglas County office at 770-920-7311.
Information about bedbugs may be found in the Georgia Department of Public Health’s Bedbug Brochure and Bed Bug Handbook.

The presence of radon in your home can have some potentially dangerous effects. Assessing the safety of your home environment can be a very simple process. Cobb and Douglas Public Health offers free kits to test radon levels in homes in Cobb and Douglas counties.
Radon, a radioactive gas, has been identified as a leading cause of lung cancer, second only to cigarette smoking in the United States. The Environmental Protection Agency’s most recent health risk assessment estimates 21,000 lung cancer deaths each year are caused by radon.
You can’t see or smell radon because it is a colorless, odorless gas. Radon is a decay product of uranium and occurs naturally in soil and rock, and levels can vary in homes. Other sources of radon include well water and building materials.
