At Marichal’s Pest Control, we specialize in targeted ant extermination to eliminate entire colonies and prevent reinfestations.
Why Ants are a Concern
Ants may seem harmless, but they can cause significant problems in your home or business.
Food Contamination & Health Risks
- Ants carry bacteria and contaminate food surfaces, leading to potential health concerns.
- Odorous house ants and other species quickly infest kitchens and pantries, making food unsafe.
Structural Damage from Carpenter Ants
- Carpenter ants tunnel through wood, weakening floors, walls, and furniture over time.
- If left untreated, these ants can cause expensive structural repairs.
Persistent & Growing Infestations
- Ant colonies grow rapidly, and killing a few ants won’t stop the infestation.
- Some species, like Argentine ants, have supercolonies, making them incredibly difficult to eliminate without professional treatment.
Signs You Have an Ant Problem
If you notice any of the following, you may have an ant infestation:
- Visible Ant Trails – Lines of ants leading to food sources in your kitchen or bathroom.
- Nests or Mounds – Dirt mounds in your yard or sawdust piles inside your home (a sign of carpenter ants).
- Food Contamination – Ants inside food containers, pantries, or pet food bowls.
- Flying Ants – Winged ants near windows or lights, particularly during warm months (a sign of colony expansion).
If you see these signs, don’t wait—professional treatment is the fastest way to eliminate ants.

Why DIY Ant Control Doesn’t Work
DIY treatments often fail to eliminate entire ant colonies. As a result, store-bought sprays may kill visible ants, but the queen remains unharmed. This means the infestation will continue growing.
Common DIY Ant Control Problems
- Partial Solutions – Over-the-counter sprays kill visible ants but not the queen, allowing colonies to regrow.
- Recurring Infestations – Without proper exclusion techniques, ants will continue returning.
- Chemical Risks – Misuse of pesticides can endanger pets, children, and non-target insects like bees.
- Increased Costs & Time – Multiple failed DIY attempts end up costing more than professional treatment.
For complete ant extermination and prevention, professional pest control is the best solution.
