Pharaoh ant (Monomorium pharaonis)

Faaraomuurahainen

The pharaoh ant is a heat-loving species that nests indoors, especially in apartment buildings and healthcare facilities. It often nests deep inside structures and can form several satellite colonies, making control challenging.

Identification

The pharaoh ant is very small, about 1.5–2.5 mm long, yellowish to light brown with a slightly darker abdomen. It often moves alone or in scattered patterns while foraging.

Habits

Pharaoh ants:

  • nest inside walls, floors, and other indoor spaces
  • prefer warm and humid areas like kitchens and bathrooms
  • are drawn to protein- and fat-rich food sources
  • can quickly form new nests if disturbed
  • move within building structures via pipes, electrical conduits, and along baseboards

Pharaoh ants may infest multiple apartments at once, turning a small issue into a widespread building-wide problem.

Control

Controlling pharaoh ants always requires professional treatment. Using insecticides independently may worsen the situation by scattering the colony.

A professional:

  • maps the colony and identifies possible satellite nests
  • uses baits specifically designed for pharaoh ants
  • coordinates treatment with property management or housing associations
  • monitors the effectiveness and provides follow-up treatments as needed
  • advises on preventive actions like sealing and improving hygiene

Summary:

Pharaoh ants are persistent indoor pests that can quickly spread throughout an entire property. They build nests within structures and are difficult to eradicate without expert help. Effective treatment involves targeted baiting, thorough assessment, and continuous monitoring.
