Whether it’s organic or inorganic mulch, all types of mulch are beneficial. As the soil thaws after the winter season, mulch preserves moisture, balances the temperature of the soil, and also shields the soil against disintegration. Mulch also prevents weeds from being open to the sun and spreading further. Many homeowners wonder if mulch around your home can lead to an uptick in bug activity. In this article, we will discuss everything you need to know about mulch attracting termites and bugs.

Does Mulch Attract Termites and Bugs?

Organic Mulch and Bugs

Organic mulch is made up of decayed vegetables, wood, grass cuttings, and compost. All of these are full of nourishment which enhances the fertility of the soil in springtime after the cold winter months. Vegetables, trees, and flowers benefit the most from organic mulch. With the decomposition of organic mulch, the soil is enriched with nutrients which enables faster growth. Despite all the benefits of organic mulch, mulch can create the perfect environment for bugs.

Mulch offers a protective shelter for bugs. The good news, bugs assist with the decomposition of the organic mulch, releasing nutrients into the soil and feeding the plant roots. The bad news, some types of bugs are harmful to plants. In fact, centipedes, mice, and termites feed on shrubs and plants, and can also target nearby buildings. Serving as shelter and food, organic mulch will attract bugs.

In order to prevent damage from bugs, use straw to attract larval predators that will minimize the bug population. Straw also poses a problem for harmful bugs to lay their eggs. Furthermore, straw deters fungal infections which result in roots rotting. Moss and peat that grow on organic mulch will ward off termites as well.

Inorganic Mulch and Bugs

Inorganic mulch is a mixture of recycled materials such as rubber, fabrics, and plastic. Pebbles, rocks, and seashells could also be utilized as inorganic mulch in your yard. Although inorganic mulch contains no nutrients, it can be repeatedly reused as it does not decompose.

Bugs, termites, rodents, and other pests won’t find any food in the inorganic mulch mixture. If the eggs of the bugs are laid in the mulch, there will be no food available for the larva. The different colors of plastics, rubber, and other inorganic materials help to repel bugs and insects. Bugs are confused by the reflection in plastics and rubber. As a result, this generally keeps bugs away from shrubs and plants surrounded by inorganic mulch.

Organic Mulch and Termites

Dangerous and expensive destruction can be caused to buildings and the foundation of your home by hazardous termites. Termites are a tremendous challenge to control once they have spread. In fact, termites are capable of infestation that cannot be detected for quite some time.

Mulch provides termites with protection and leaves them free to reproduce. Reproducing results in the creation of colonies of termites. These colonies then expand in moist environments created by rain and regular watering. Certain woods in mulch are appealing to termites as they serve as a food source. Examples of woods that termites find attractive include:

  • Cypress Sapwood
  • White Birch
  • Loblolly Pine
  • Slash Pine

Inorganic Mulch and Termites

Although there are no nutrients in inorganic mulch, mulch gives termites shelter and makes them harder to detect. Rubber, plastics, rocks, and pebbles conceal what is happening underneath the surface of the soil. The termite colony will then expand as nearby wood structures are reached. It is easy for termites to dig in the soil when moisture is retained in it. Thin tunnels are created in order to look for wood (food source). Termites can get to the deep foundations of houses and buildings, move inside, and feed on wood paneling or even furniture.

It is unlikely for termites to survive if there is no access to solid wood. Termites thrive with moisture, therefore, they are only attracted to the wood if it contains high levels of moisture for prolonged periods.

The chipping process involved in the production of commercial wood mulch dries the wood out which helps repel termites. Some woods can be toxic and will even destroy termite colonies. Applying these types of mulch can help get termite infestations under control:

  • Southern Tidewater Red Cypress
  • Cypress Heartwood
  • Eucalyptus
  • Cedar
  • California Redwood


Mulch will not attract termites but also shelters them if they are already present. Some bugs are in fact beneficial to organic mulch, as they assist in its decomposition which then releases nutrients into the soil. While termites can pose a serious threat to any wood structure, there are preventative measures that can be taken to ensure applying mulch to your lawn and landscape will not attract termites.
