Does mulch attract ants? This is a question many gardeners have when considering if they should mulch their gardens. Mulches are traditional soil coverings used in gardens to protect and enrich the soil, while also keeping weeds down and improving water retention. 

This is why mulch is a popular choice for gardeners, but there is one downside – a mulched area can actually attract ants. In this blog post, we’ll discuss why mulch can attract ants, and what you can do to minimize ant invasions in your garden.

Does Mulch Attract Ants?

Yes, mulch can generally attract ants, especially wood mulch. Ants tend to be drawn to wood chips and bark mulch because these surfaces provide them with protection from the elements. Mulch can also contain food sources for the ants, such as small pieces of organic matter, such as leaves, and the insects that feed on them. Plus, mulch often contains other insects, like termites and beetles, which make up part of the ants’ food source, making it the ideal environment. Carpenter ants and other types of ants and garden pests will be attracted to almost any type of mulch or woody materials, with the exception of cedar mulch or cedar chips, which tends to deter most pests. Cedar trees have natural oils with a strong smell that deters most pests.

Signs of An Ant Infestation

If you’re looking for signs that you have an ant infestation, the best way to tell is by checking the list below. 

  • Look for small dirt piles near your home or property. Ants will often make small piles of dirt around the entryways to your home. 
  • Check for ants in the kitchen. Tiny black ants or large, red fire ants can commonly be found in the kitchen, near food and water sources. 
  • Inspect areas around windows and doors to see if there are ants coming and going. Check for ants on the walls as well. 
  • Inspect any windowsills or doorframes to see if they are getting frequent ant activity. 
  • Look for ants in your garden, around plants, or around your compost pile. 
  • Examine your mulch bed or any other areas where debris has been allowed to accumulate. These spots can be prime nesting spots for ants and unwanted pests. 
  • Check plants or trees around your home for signs of ant activity. Ants will sometimes take up residence in young trees or in the crevices of stumps. 
  • Check for small ant colonies around the foundation of your home, or in outdoor spaces near your home.

Prevention and Control     

How to discourage ants from entering your property

  • Shut all windows and doors tightly and seal any potential entry points. 
  • Keep food and drinks inside tightly sealed containers, and make sure all food waste is disposed of properly. 
  • Keep your house clean and tidy to reduce any potential food sources that may attract ants. 
  • Sprinkle and spread insecticide dust (pyrethrum, diatomaceous earth, or boric acid) around the perimeter of your home. 
  • Place ant baits or traps around the perimeter of your home and in areas where ants might come in. 
  • Put plants that naturally repel ants, such as mint and citronella, around the perimeter of your home or use essential oils like cedar oil. 
  • Block ants’ potential routes of entry by sealing any small cracks or holes. 
  • Remove sources of moisture that ants may be attracted to, such as leaky pipes and wet mulch. Reroute down spouts away from mulch beds.
  • Make sure that all outdoor garbage cans are tightly sealed and that no food or other materials are left outdoors. 
  • Create a barrier outside your home by sprinkling salt, black pepper, chili flakes, or cayenne pepper near all possible entry points.

Steps to reduce the risk of ants entering mulch 

1. Keep mulch and planting beds well-trimmed and free of garden debris. 

2. Try using inorganic materials for mulch like rubber mulch, plastic mulch, or another similar kind of mulch, instead of wood products that attract all types of bugs.

3. Create a barrier of diatomaceous earth around the perimeter of the mulch or planting bed. 

4. Apply an insecticide or an organic ant control product around the perimeter of the mulch or planting bed. 

5. Use sticky barriers such as double-sided tape or sticky traps in areas that attract ants. 

6. Ensure adequate drainage in the garden or mulch to prevent reduced soil moisture, which can attract ants. 

7. Keep food, drinks, and pet food away from the mulch or planting bed. 

8. If the infestation is large and persistent, call a pest control professional for advice and treatment.

Ways to Control an Existing Ant Infestation

  • Use baits – Luring the worker ants with a bait formulated with an insecticide will help poison the entire colony, including the queen. 
  • Vacuum – If ants have made their way from your flower bed into your home, vigorous cleaning of food sources and corners and crevices in which the ants have been more frequent will discourage them by removing their food sources. 
  • Seal entryways – Small cracks or crevices are the perfect place for ants to enter your home. Repairing these areas through which the ants have been entering will prevent them from coming back. 
  • Make your property unattractive – Avoid leaving food items in the open as it is a major attraction for ants. Grease and food particles must be wiped off dishes, tables, and countertops. 
  • Professional Pest Control Treatment – If your ant problem is worse than you can handle on your own, consider a professional exterminator. Considering the potential problems that a pest infestation can cause, this is sometimes the most effective way to handle insect activity.
