HOW TO GET RID OF ANTS USING DIATOMACEOUS EARTH

HOW TO GET RID OF ANTS USING DIATOMACEOUS EARTH

Using diatomaceous earth can be an effective and natural way to get rid of ants. Here’s how to use it to tackle an ant problem safely.

Step 1. Gather the Necessary Tools and Materials

Begin by collecting everything you need for the task. For safety around pets and kids, you will need food-grade diatomaceous earth made from the fossilized remains of diatoms.

You will also need a duster or a spray bottle to apply the powder. A dust mask and protective gear from Amazon can help you avoid inhaling the fine powder.

Step 2. Put on Protective Gear

Before you start, put on your protective gear. Diatomaceous earth is a fine white powder. While it isn’t toxic, it can irritate your lungs and eyes. Wearing a dust mask, gloves, and safety goggles will help you avoid discomfort.

Step 3. Identify Ant Trails and Entry Points

Ants leave behind pheromones that create trails for other ants to follow. Locate where they are coming from and where they travel.

Look for ant trails along baseboards, window sills, and entry points like doorways. Identifying these paths will help you target your application effectively.

Step 4. Apply Diatomaceous Earth Indoors

Sprinkle a thin layer along the ant trails and entry points indoors. With its sharp edges, the silica in the diatomaceous earth works by damaging the exoskeletons, ultimately killing them. 

Apply it lightly so it remains effective without creating excessive dust.

Step 5. Apply Diatomaceous Earth Outdoors

For outdoor use, focus on the perimeter of your home, especially near entry points and ant colonies. Apply the diatomaceous earth around gardens, patios, and foundations.

This will prevent ants from entering your home and reduce the chances of an ant infestation.

Step 6. Track and Reapply as Necessary

Track the areas where you applied diatomaceous earth. If you notice these crawling insects reappearing, you should reapply the powder.

Weather conditions such as rain can reduce the effectiveness of outdoor applications. This condition necessitates more frequent reapplications.

Step 7. Clean Up Excess Diatomaceous Earth

Once you’re confident that the ant problem has been resolved, it’s time to clean up any excess diatomaceous earth.

Since diatomaceous earth is a naturally occurring sedimentary rock, use a vacuum for indoor cleanups. For outdoor areas, use a broom or hose. Ensure a thin layer remains in critical areas to prevent future infestations.

Common Mistakes to Avoid When Using Diatomaceous Earth

By following these tips, you can improve the effectiveness of diatomaceous earth for your DIY pest control.

  • Not Using Food-Grade DE: It’s essential to use food-grade DE. Industrial-grade or pool-grade DE may contain additives that can harm humans and pets.
  • Applying Too Much: People often think that more is better. Over-applying diatomaceous earth can temporarily deter ants, but it may cake up and become less effective.
  • Inappropriate Application Areas: Diatomaceous earth should be applied in dry areas. Wet environments can render it ineffective. Use it along dry areas and other entry points.
  • Ignoring Other Insects: Diatomaceous earth can also kill mites, earwigs, cockroaches, bed bugs, and fleas. When treating your home, pay attention to these pests as well.
  • Skipping Monitoring: Regularly check the treated areas. Sometimes, it may take a few days to see results. If there’s no progress, extra treatment might be necessary.
