Ants look pretty harmless, but are they, really?

Common ant species in the Philippines

Crazy Ant

Paratrechina spp.

Appearance: Dark-colored

Size: 4mm

This ant is commonly found in outdoor and indoor areas, and is distinguished by its erratic movement. They usually stay in the cracks and crevices of your home or building, especially if there is good moisture or warmth. Because of their ability to produce large colonies, their infestation in buildings can be very extensive.
Tropical fire Ant

Solenopsis geminata

Appearance: Light to golden brown

Size: 3-6mm

These ants can bite and sting, causing reddish swells that can be really itchy or uncomfortable for more sensitive people. They are normally outdoor ants, but can also enter homes and buildings when they scavenge for food. They can also nest and establish new colonies in new territories.
Pharaoh Ant

Monomorium pharaonis

Appearance: Yellow or light brown

Size: 2mm

Believed to have originated from Egypt, these widely-distributed ant species is one of the biggest headaches for home and building owners because of the fast spreading of their colonies. These ants are very small, and are able to hide in tight spaces and crevices like wall cracks.
