Pharaoh Ants
Pharaoh ants form sprawling colonies indoors and can spread pathogens in healthcare settings.
Background & Behavior
(Monomorium pharaonis) Tiny and yellowish, pharaoh ants form large colonies inside walls, appliances, and baseboards. They are notorious for infesting hospitals, kitchens, and pantries, spreading pathogens through food and surfaces. Colonies split easily, making control difficult. Baiting systems work better than sprays for long-term management.
DIY Approaches
- Use non-repellent bait stations in warm, humid areas where trails are seen.
- Avoid spraying over-the-counter insecticides that cause colonies to bud.
- Seal food and medical supplies in airtight containers.
- Wipe counters with mild soapy water to remove scent trails.
- Fix plumbing leaks quickly to eliminate preferred moisture sources.
Professional Services
- Engage commercial pest experts for complex baiting strategies across entire buildings.
- Request regular monitoring in hospitals, nursing homes, and food facilities.
- Have professionals map colony routes using fluorescent baits for precision.
- Coordinate staff training on sanitation and storage protocols.
- Schedule follow-up visits to adjust bait placements as colonies shift.
