Which Mulch Does Not Attract Termites?
Termites are a subterranean insect that feed on moisture and wood. They are a very small and unseen pest that can cause serious damage to a home’s foundation. If you are unsure about whether your mulch is being infested, it is advisable to contact a reputable professional for a diagnosis.
Termites are attracted to mulches that are very moist and provide good cover for underground tunneling. Creating a buffer zone around your house will help deter termites from tunneling into the structure.
The University of Florida/IFAS Structural IPM Program tested several types of landscape mulches to see how they affected termite activity. They found that pine bark, gravel, and pea gravel mulches had similar rates of detection of termites.
The only thing that attracts termites to mulch is moisture. Therefore, the type of mulch you choose should not be placed directly over your foundation. Instead, create a buffer zone about six inches away from the wall. This will prevent moisture from seeping into your home and the soil.
Using organic mulches such as cypress or melaleuca can help deter termites. These materials are more resistant to termite feeding than wood mulch. In addition, they are also more environmentally friendly.
Alternatively, inorganic mulches such as ground rubber or ash may not attract termites. These are usually more economical than organic options. However, they can make the soil hotter, which is not good for termites.
When selecting a mulch, make sure it is at least three inches thick. This is so it can provide termites with a better environment.
