Pharaoh ants are very small, light-coloured ants that thrive indoors, especially in warm buildings. They’re difficult to control because colonies can split into multiple nests when disturbed by the wrong sprays or DIY attempts. That’s why infestations can spread instead of improving. You may see them near kitchens, bathrooms, and wall gaps. Proper identification and bait-based treatment are key, so it’s best to bring in a professional.
