Controlling Mold with Antimicrobial Pesticides

mold on walls

Molds produce tiny invisible spores as they reproduce that are found almost everywhere. Mold spores do not grow unless they find some moisture. If you have a mold problem in your home, you must also have a moisture problem. Finding and eliminating the moisture source is the key to controlling mold.

Here are some other tips to keep in mind:

  • Outside the home mold plays an important role in breaking down dead organic matter (such as leaves), thus mold spores are everywhere and there is no way to completely eliminate mold spores indoors or outdoors.
  • In order for mold spores to grow, they need moisture, so controlling mold growth can be as simple as preventing moisture in your home.
  • In the event of a leak or flood, clean and dry any damp or flooded materials and furnishings as soon as possible to prevent mold growth.
  • Decreasing the humidity in your house can help to control mold.
  • Hard non-porous surfaces can sometimes be cleaned of mold growth, but absorbent materials like carpeting and drywall may have to be replaced if they become moldy.
  • Make sure any antimicrobial product you select to treat a mold problem is designed specifically for treating your situation. If in doubt, call an NPIC specialist for assistance before using the product.
  • When using antimicrobials, always read and follow all label directions carefully. Make sure you are mixing and applying the product specifically as the label directs and do not use more than you are directed to use on the label.
