Common Ant Species in Redmond
Understanding which type of ant you're dealing with is the first step toward effective control. Redmond's climate and environment are hospitable to several common species, each with distinct behaviors and nesting preferences.
Odorous House Ants: True to their name, these small, dark brown or black ants emit a rotten coconut-like smell when crushed. They are the most frequent indoor invaders, drawn to sweets and moisture. Their colonies can be large with multiple queens, making them a recurring problem if not fully addressed 1.
Carpenter Ants: These are larger, black or red-and-black ants that pose a significant threat to property. Unlike termites, they do not eat wood but excavate it to create smooth tunnels and galleries for nesting. They are attracted to damp, decaying, or water-damaged wood, often in wall voids, attics, crawlspaces, and around window frames 2 3. Spotting large, winged "swarmer" ants indoors is a strong indicator of an established colony within the structure.
Pavement Ants: Typically nesting under sidewalks, driveways, and foundation slabs, these small brown or black ants enter buildings in search of food. They are commonly seen trailing along edges and can become a persistent kitchen pest 1.
Moisture Ants: Often confused with carpenter ants, these yellow to dark brown ants are strongly attracted to high-moisture areas and rotting wood. Their presence is a red flag for a potential moisture issue in your home that needs to be corrected alongside pest treatment 4.
Where to Look for Ant Activity
Ants are opportunistic, seeking food, water, and shelter. Knowing their favorite hideouts can help you identify an infestation early.
- Kitchens and Bathrooms: These are prime targets due to accessible food particles, sticky residues, and water sources. Check under sinks, around appliances, along baseboards, and in pantry corners for trails of odorous house or pavement ants 1 5.
- Wall Voids and Structural Wood: Carpenter and moisture ants favor these hidden areas, especially where wood is in contact with soil or has sustained water damage. Listen for faint rustling sounds inside walls and inspect for small piles of sawdust-like "frass" near baseboards or window sills 2 6.
- Attics and Crawlspaces: These often-neglected spaces provide ideal, undisturbed nesting sites for carpenter ants. Regular inspections for ant activity or damaged wood here are important for early detection 1.
- Exterior Entry Points: Ants exploit the smallest gaps. Common invasion routes include cracks in the foundation, gaps around utility lines, door and window frames, and where siding meets the roofline 1.
- Yards and Gardens: Outdoor nests are frequently built in exposed soil, under stones, pavement, landscaping timbers, or piles of firewood or organic debris. Trails often form along fence lines, walkways, and the foundation 4.
The Professional Ant Extermination Process
Professional pest management for ants in Redmond follows an Integrated Pest Management (IPM) approach, which prioritizes long-term prevention and minimal environmental impact 7 8. Here's what a comprehensive service typically entails:
-
Inspection and Identification: A technician will conduct a thorough inspection of your property, inside and out, to identify the ant species, locate nests (both indoor and outdoor), trace foraging trails, and pinpoint entry points and conducive conditions like moisture problems 1 2.
-
Targeted Treatment Plan: Based on the inspection, a customized plan is developed. This rarely relies on a single method but uses a combination of strategies for maximum effectiveness:
- Baits and Traps: Specially formulated baits are placed where ants are active. Worker ants carry the bait back to the colony, sharing it with the queen and larvae, leading to colony collapse. This method is highly effective for many species, including odorous house ants 9 10.
- Exterior Perimeter Barrier: A protective, often non-repellent, insecticide is applied around the foundation, doorways, and other potential entry points. This creates an invisible barrier that eliminates ants as they attempt to cross it 11 12.
- Direct Nest Treatment: For accessible nests, technicians may use insecticidal dusts or sprays applied directly into wall voids, attic spaces, crawlspaces, or outdoor mound nests 13.
- Exclusion Recommendations: While not always included in standard treatment, a professional will advise on sealing cracks and gaps to prevent future access, which is a critical step for long-term control 1.
-
Follow-up and Monitoring: Ant control is often not a one-and-done service. Follow-up visits are scheduled to monitor bait stations, check for remaining activity, and re-treat specific areas if necessary. This ensures the colony is completely eradicated 14 9.

What to Expect After Treatment
Patience is key after a professional ant treatment. You can typically expect to see a noticeable reduction in visible ant activity within a few days. However, complete elimination can take several days to a few weeks 14 15. This is especially true with baiting systems, which are intentionally slow-acting to allow the bait to be distributed throughout the entire colony, including the queen 16 17. You may even see increased ant activity near bait stations initially-this is normal and indicates the bait is being taken. It's crucial not to spray or disturb these ants or the bait stations.
Understanding Ant Control Costs in Redmond
The cost for professional ant extermination in Redmond varies based on the severity of the infestation, the species involved, the size and layout of your property, and the company you choose 11. Below is a general overview of potential costs:
| Service Type | Estimated Cost Range | Key Considerations |
|---|---|---|
| One-time Treatment | $80 - $500 | Best for minor, localized infestations or early intervention. Cost depends on property size and treatment scope 11 18 3. |
| Severe or Widespread Infestation | Up to $1,400+ | Complex cases, like large carpenter ant colonies in structural wood, may require multiple visits, advanced methods, and could involve repair work for damaged wood 11. |
| Carpenter Ant Treatment | $250 - $500+ | Typically higher due to the difficulty in locating hidden nests and the potential for property damage. Requires specialized inspection and treatment 3. |
| Preventive Quarterly/Annual Plans | $400 - $500 per year | Many homeowners opt for ongoing plans that include scheduled treatments (e.g., quarterly) to prevent ants and other common pests. These often provide free service calls between visits 11 19. |
The most accurate way to determine cost is to request a free inspection and estimate from a local Redmond provider. Companies like Parker Eco Pest Control and Eastside Exterminators offer these consultations to assess your specific situation 10 19 20 21.
