How to Get Rid of Argentine Ants in Santa Clarita: What You Need to Know & How to Protect Your Home
The Problem with Argentine Ants in Santa Clarita
As pest control technicians in Santa Clarita, we deal with Argentine ants on the regular. These invasive pests are a common problem for homeowners and businesses across the valley. Unlike typical ant species that form distinct, competitive colonies, Argentine ants (Linepithema humile) create massive interconnected super-colonies, making them difficult to control.
As you can imagine, the main problem with Argentine ants is their sheer numbers and resilience. When disturbed, they quickly relocate and even break off into satellite colonies, making DIY treatments ineffective. They also displace native ant species, disrupt ecosystems, and invade homes searching for food and water. Worse yet, they can infest electrical equipment, short-circuiting appliances and causing costly damage.
Key Takeaways:
- Unlike many ant species, Argentine ants have multiple queens per colony, allowing them to reproduce rapidly, expand to satellite colonies, and recover from partial extermination, oftentimes making DIY methods largely ineffective.
- Argentine ants are small (about 1/8 inch), light to dark brown, and travel in long, organized trails rather than scattering when disturbed.
- They are drawn to sugary foods, protein, moisture, and warm sheltered areas, making kitchens, bathrooms, and outdoor spaces common infestation sites. They can adjust their food preferences based on colony needs.
- These ants do not bite or sting, but they contaminate food, invade electrical systems, and disrupt local ecosystems by displacing native species.
- Argentine ants are highly adaptable and thrive in Santa Clarita’s warm climate, often nesting in wall voids, gaps near plumbing fixtures, soil, and under debris.
- Sealing entry points, reducing moisture, and eliminating food sources can help minimize infestations but won’t completely eradicate an established colony.
- Baiting is one of the most effective ways to eliminate Argentine ants, as they carry the product back to the colony to share with other ants.
- No Bugs offers professional Argentine ant control in Santa Clarita with advanced baiting techniques, same-day service, and a lifetime price guarantee!

Are There Argentine Ants in Santa Clarita?
Yes, Argentine ants are widespread in Santa Clarita. Our wonderful city’s warm climate (sometimes too warm!) and urban landscaping provide ideal conditions for these ants to thrive. They’re commonly found in residential neighborhoods, business complexes, and even outdoor recreational areas.
If you’ve noticed large trails of tiny brown ants marching along sidewalks, driveways, or your kitchen counters, chances are you’re dealing with Argentine ants!
Why Are Argentine Ants Bad for SCV Residents?
While these pesky invaders originate from Argentina in South America, Argentine ants can now be found in various parts of the world where they thrive as a prevalent pest. In fact, they are one of the most common ant species found in Southern California.
Their resilient adaptability allows them to thrive in various environments, making them a frequent invader in homes and gardens.
Santa Clarita homeowners often struggle with Argentine ant infestations due to their invasive nature and the threats they pose to property and the local ecosystem. For example:
- Difficult to Eliminate – These colonies can be massive with multiple queens, making traditional and DIY ant control methods ineffective.
- Food Contamination – They forage aggressively and can contaminate food in your kitchen.
- Damage to Electrical Systems – They’re known to invade circuit boards, HVAC systems, and even car engines.
- Harmful to Native Species – They outcompete and eliminate native ants (I know, probably not your first worry) and beneficial insects.
- Encourage Other Pests – Argentine ants are known to protect honeydew-producing pests like aphids and scale insects, worsening plant infestations.
How Do You Identify an Argentine Ant?
These ants are typically light to dark brown and measure about 1/8 inch in length. They are often found in shallow nests in the ground but can also establish colonies indoors, especially in moist areas. A distinguishing feature is their tendency to form large colonies with multiple queens, which contributes to their rapid spread and resilience.
Argentine ants are small but distinct if you know what to look for. Here are their key characteristics:
- Size: About 1/8 inch (2.2–2.8 mm) long.
- Color: Light to dark brown.
- Shape: Slender bodies with a single node (waist segment) where the thorax connects to the abdomen.
- Behavior: They move in continuous, noticeable trails and do not swarm aggressively when disturbed.
- Smell: When crushed, they emit a musty odor.
If you notice large numbers of uniform-looking ants moving in long, organized trails, you might be dealing with Argentine ants!

What Attracts Argentine Ants?
The big questions: Why you? And why your home?
Unfortunately, there is no easy answer or trick to avoiding any ant infestation. In the words of the crusty Mad-Eye Moody, it comes down to “Constant Vigilance!” Especially in summer when ants are marching for water and shelter from our scorching summers.
Argentine ants are attracted to a variety of foods, particularly sugary substances. They also like aphid, mealybug, and scale insect colonies, harvesting the honeydew produced by these pests, which can lead to increased ant populations in affected areas.
Argentine ants are drawn to moisture and food sources. Some of the biggest attractants include:
- Sugary Foods – Spilled soda, fruit juices, honey, and even houseplants infested with aphids.
- Proteins and Grease – They will go after pet food, meats, and greasy leftovers.
- Standing Water – Leaky pipes, irrigation systems, and condensation provide them with hydration.
- Warm, Sheltered Areas – Potted plants, cracks in pavement, and wall voids offer safe nesting spots.
Sealing up entry points and eliminating food sources can help reduce infestations.
What Do Argentine Ants Eat?
As mentioned before, Argentine ants are incredibly resilient pests (unfairly so). For instance, they are considered opportunistic eaters with a highly adaptable diet. Their food preferences can shift based on the colony’s needs, making them difficult to target with a single baiting approach.
Their primary food sources include:
- Sugary Substances – Honeydew, fruit juices, nectar, and spilled sugary drinks.
- Proteins – Dead insects, pet food, meat scraps, and grease.
- Oils and Fats – Cooking oils, peanut butter, and other lipid-rich substances.
- Water Sources – Argentine ants are highly dependent on moisture and will seek out leaks, condensation, and damp areas inside homes.
Because their diet is varied, using both sugar-based and protein-based baits at different times is the most effective way to eliminate infestations. And even that might not be enough, which we will get into in more detail below!
Are Argentine Ants Harmful to Humans?
Argentine ants are annoying, challenging to exterminate, and can do damage to your stress levels. However, they do not bite or sting, and they are not directly harmful to humans in the way that fire ants or venomous insects are.
That said, they can still pose significant issues in homes and businesses:
- Food Contamination: Argentine ants forage in large numbers and can contaminate food, utensils, and cooking surfaces, spreading bacteria.
- Allergies and Respiratory Issues: While rare, some people may experience allergic reactions from exposure to ant trails, particularly if they have pre-existing respiratory conditions.
- Pest Facilitation: Argentine ants protect and "farm" other pest species like aphids and scale insects, indirectly leading to plant damage and increased insect infestations around homes (rude).
Although they are not dangerous in the traditional sense, their overwhelming presence and ability to invade food sources make them a major nuisance pest that should be controlled quickly.
Do Argentine Ants Nest in Walls?
The general rule for ants is that they don’t typically live in walls due to a lack of resources.
With that said, while Argentine ants prefer nesting in moist environments such as under debris or within soil, they have been known to establish nests indoors, especially in areas with moisture issues. This adaptability allows them to exploit various habitats, making control efforts more challenging.
So, yes: Argentine ants can establish nests inside wall voids if the environment caters to their survival. In fact, they can nest in a lot of unfortunate places, including but not limited to:
- Wall cavities near kitchens and bathrooms.
- Spaces behind cabinets and baseboards.
- Attic insulation.
- Under carpets.
- Gaps near plumbing fixtures.
- Insulation and electrical boxes.
- Potted plants.
Because their nests can be hard to locate, professional pest control methods are often needed to fully eliminate them from homes.
Fortunately, the Santa Clarita ant control experts at No Bugs are armed and ready to tackle the challenge! We can inspect your property and complete a comprehensive treatment plan that focus on exclusion, baiting, and other critical tactics to rid your home of these obnoxious invaders.
What Time of Day Are Argentine Ants Most Active?
Argentine ants are most active at night and early in the morning. During these times, you may see long trails of ants moving between their nests and food sources. However, they will also remain active throughout the day, especially in shaded or indoor environments.
Do Argentine Ants Eat Termites?
Okay, time to put a stop to some rumors! While Argentine ants have been observed attacking termites, they don’t actively hunt them as a primary food source. They are opportunistic feeders and may feed on weakened termite colonies, but they are not an effective form of termite control. In fact, their presence can sometimes make termite problems worse by disrupting traditional termite baiting methods.
How Big Is an Argentine Ant Colony?
Argentine ant colonies can contain millions of workers and multiple queens. Unlike most ant species, where separate colonies fight for territory, Argentine ants form massive interconnected super-colonies. In California, these super-colonies can stretch for hundreds of miles, making them nearly impossible to eliminate completely without professional intervention.
Fun fact: In California, a notable super-colony, referred to as the “Very Large Colony,” extends from San Diego to beyond San Francisco. This colony covers a vast area and contains an immense population of ants.
Do Argentine Ants Have Multiple Queens?
Yes, Argentine ants are polygynous, meaning their colonies have multiple queens. This is one of the reasons they spread so aggressively. If a portion of a colony is disturbed or separated, the queens quickly establish new nests, making extermination efforts more challenging.
Unfair, right?
How Do You Find an Argentine Ant Nest?
Tracking an Argentine ant nest can be difficult because they don’t have a single central nest. Instead, they create satellite nests in various locations. To locate a nest, follow these steps:
- Observe Their Trails – Ants will typically move between a food source and their nesting site.
- Check Moist Areas – They prefer damp environments such as near leaking pipes, potted plants, or under kitchen sinks.
- Inspect Wall Voids and Outdoor Spaces – Look for ants emerging from cracks, foundation gaps, or soil near your home.
Because they frequently move nests, professional pest control solutions are the most effective way to target their hidden colonies.
4 Tips to Get Rid of Argentine Ants in Santa Clarita
Effective pest control management for Argentine ants often involves baiting strategies based on their behaviors, colony location, and dietary preferences, which can vary based on environmental factors and the colony’s needs. While Argentine ants are generally attracted to carbohydrate-rich foods, their preference for proteins can increase during certain periods, such as when nurturing their brood.
Eliminating Argentine ants requires a combination of exclusion, baiting, and professional treatment. It is highly recommended that you contact experienced and qualified pest control provider to help you manage an Argentine ant infestation.
Here’s a list of 4 tips to help you tackle the problem!
1. Remove Food and Water Sources
- Store food in sealed containers.
- Clean up spills and crumbs immediately.
- Fix leaky pipes and reduce moisture around the home.
2. Seal Entry Points
- Caulk cracks and gaps around doors, windows, and pipes.
- Repair damaged weather stripping and screens.
3. Use Ant Baits
- Baiting is the most effective method because Argentine ants bring the product back to their colony.
- Use sweet gel baits (e.g., borax-based) for indoor control.
- Use protein-based baits outdoors to target satellite nests.
Pro Tip: It’s essential to monitor the ants’ feeding behaviors and adjust bait types accordingly to enhance effectiveness. Additionally, maintaining sanitation and sealing entry points are crucial steps in preventing and managing infestations.
4. Call a Professional Pest Control Service
Because of their supercolony behavior, complete eradication is nearly impossible if you rely on DIY methods alone. While you might take care of a trail, there could be millions of other ants ready to follow that pheromone trail into your home.
