Easy Methods to Get Rid of Ants on Your Patio

Ants are a common outdoor nuisance, particularly on patios. They can ruin outdoor gatherings, infest the garden, and even find their way indoors. While some ant species may be harmless, others can pose a threat to humans and pets, making it crucial to identify and manage the infestation as soon as possible. To get rid of them for good, follow these simple steps:

  1. Identify the source: Locate the ant nest or entry points to determine the source of the problem.
  2. Remove food sources: Clean your patio thoroughly, removing any food or drink spills that may attract ants.
  3. Block entry points: Seal any cracks or gaps in your patio’s structure or foundation to prevent ants from entering.
  4. Natural repellents: Use natural repellents such as vinegar, lemon juice, or peppermint oil, as ants dislike these scents. Apply these repellents along the ant trails and entry points.
  5. Bait stations: Place ant bait stations near the ant trails or nests. Ants will carry the bait back to the nest, effectively eliminating the colony.
  6. Diatomaceous earth: Sprinkle food-grade diatomaceous earth around the patio. This powder damages ants’ exoskeletons and dehydrates them.
  7. Regular maintenance: Keep your patio clean and free from debris to discourage ants from returning.

If the ant infestation persists or becomes severe even after you’ve taken all the steps that we’ve mentioned, it may be necessary to consult with a professional pest control service for more targeted treatment options.

Identifying the Ant Species

Why it’s important to know the ant species

There are over 1,200 different ant species. Each species behaves and responds differently to pest control methods. Knowing the ant species found on the patio can help determine the most effective solution.

Common ant species found on patios

The following are some common ant species found on patios:

  1. Carpenter ants: These ants are typically large and black and are often found in wood structures. They do not eat wood but excavate tunnels for nesting.
  2. Pavement ants: These ants are small and brown and often build their nests in pavement cracks or under rocks.
  3. Fire ants: These ants are small and reddish-brown and deliver a painful sting when threatened. These ants alone cause over £3 billion worth of damage a year!
  4. Argentine ants: These ants are brown and are found in large colonies. They are known for their ability to displace other ant species and can cause damage to plants.

Methods for identifying ant species

The following are some methods for identifying ant species:

  1. Physical characteristics: Ants have distinct physical characteristics such as color, size, and body shape that can help identify the species.
  2. Behavior patterns: Different ant species have unique behaviors such as nesting habits, food preferences, and aggression levels.
  3. Local geographical distribution: Some ant species are more common in certain areas than others, making it easier to identify the species based on geographical location.

Preventive Measures

Importance of prevention

Prevention is the most effective way to control ant infestations. It’s important to eliminate attractants and seal entry points to prevent ants from accessing the patio.

Sealing cracks and gaps

Ants can enter the home through even the smallest cracks and gaps. Seal any openings, including around doors and windows, to prevent ants from accessing the patio.

Proper food storage and waste management

Ants are attracted to food and waste. Proper food storage and waste management can help reduce the likelihood of an ant infestation. Store food in airtight containers and dispose of waste regularly.

Biological control methods

Biological control methods involve introducing beneficial insects or organisms to control ant populations. The following are some biological control methods:

  1. Introducing beneficial insects: Introducing beneficial insects such as ladybugs and lacewings can help control ant populations.
  2. Using nematodes: Nematodes are microscopic worms that can be applied to the soil to control ant populations.

Chemical Solutions

When to consider chemical solutions

Chemical solutions should be considered only as a last resort when natural and eco-friendly solutions fail. It’s important to read and follow the label instructions carefully.

Types of chemical insecticides

The following are some types of chemical insecticides:

  1. Contact insecticides: Contact insecticides can kill ants on contact.
  2. Insect growth regulators (IGRs): IGRs can interfere with the growth and development of ants, eventually leading to their death.
  3. Fumigants: Fumigants can be used to eliminate ant colonies in enclosed spaces.

Frequently Asked Questions

Let’s answer the most frequently asked questions about ants on patios.

1. How to Seal Entry Points for Ants?

To seal entry points for ants, start by locating their entryways and tracing their trails. Then, use caulk or silicone sealant to seal any cracks, gaps, or holes they use to access your home. Ensure windows and doors are properly sealed, and install door sweeps and weather stripping. Keep your home clean, especially in the kitchen, and store food in airtight containers. Eliminate standing water sources and fix plumbing leaks. Additionally, consider using ant baits or natural deterrents to discourage ants from entering. Regularly inspect and maintain the sealed areas to prevent new entry points from forming.

2. How Do I Permanently Get Rid of Pavement Ants?

To permanently get rid of pavement ants, start by eliminating potential food sources by keeping your premises clean and storing food in airtight containers. Seal any entry points they use to access your property, such as cracks and gaps in walls or windows. Use ant baits or natural remedies like diatomaceous earth or vinegar to deter and kill ants. If the infestation persists, consider seeking professional pest control services for more effective and targeted treatment. Regular monitoring and maintenance are essential to prevent future infestations.

3. How Do I Get Rid of Ants In My Pavers Naturally?

To naturally get rid of ants in your pavers, try these methods. First, sprinkle diatomaceous earth or cinnamon powder along the ant trails and entry points to deter them. Alternatively, mix equal parts of water and white vinegar, then spray the solution on the affected areas. Ants dislike the smell of vinegar and will avoid it. Additionally, create a barrier using citrus peels, coffee grounds, or mint leaves, as ants dislike these scents. Regularly sweep and clean the area to eliminate food sources. Finally, consider planting ant-repellent plants like lavender or peppermint near the pavers to discourage them.

4. What Is the Best Homemade Outdoor Ant Killer?

A simple and effective homemade outdoor ant killer involves mixing equal parts white vinegar and water, adding a few drops of dish soap, and spraying the solution directly onto ant trails, nests, and entry points. The vinegar disrupts the ants’ pheromone trails, while the soap helps to suffocate them. Another option is a mixture of borax and powdered sugar, which attracts ants but ultimately kills them. Remember to use caution when handling or placing these mixtures, and consider seeking professional pest control advice for severe infestations.

5. Does Vinegar Kill Ants Outdoors?

Vinegar can help deter ants due to its strong odor, but it may not necessarily kill them. While vinegar disrupts the ants’ scent trails and makes the area less appealing to them, it is not a potent insecticide. For outdoor ant control, using vinegar as a temporary solution or in combination with other methods like sealing entry points, removing food sources, or deploying ant baits may be more effective in managing ant populations. Consulting with a professional pest control service can provide tailored solutions for your specific ant problem.


Ants can be a pesky and persistent problem on patios, but with the right strategies, they can be eliminated and prevented from returning. It’s important to identify the ant species, use preventive measures, and consider natural and eco-friendly solutions before resorting to chemical solutions or professional pest control. Routine inspections and monitoring, ongoing preventive measures, and adjusting strategies as needed can help maintain a pest-free outdoor living space. Remember, prevention is key, and taking eco-friendly approaches can be better for the environment and the health of your family and pets.
