Ants are social insects that live in organized colonies and can become a significant pest when they invade homes and commercial establishments. Although some species are beneficial to the ecosystem, others can cause structural damage, contaminate food, and cause discomfort. Ant pest control requires a strategic approach to eliminate not only visible ants but the entire colony.

Main Species of Urban Ants

• Pharaoh Ant (Monomorium pharaonis): Small, yellowish, prefers warm and humid environments. Common in hospitals and residences.
• Argentine Ant (Linepithema humile): Light brown, forms supercolonies and is very aggressive towards other species.
• Carpenter Ant (Camponotus spp.): Large, black, excavates wood to make nests, causing structural damage.
• Fire Ant (Solenopsis spp.): Small, reddish, has a painful sting and can cause allergic reactions.

Ant Pest Control Methods

1. Ant Baits

Baits are the most effective method for ant control. They contain food attractants mixed with slow-acting insecticides. Worker ants carry the bait back to the nest, feeding the queen and larvae, eliminating the entire colony.

2. Insecticide Gel

Applied at strategic points where ants travel. The gel is attractive and the ants transport it to the nest, contaminating the entire colony.

3. Spraying

Used to quickly eliminate visible ants and create a residual barrier. Most effective when combined with baits.

4. Chemical Dust

Applied in cracks, crevices, and ant passage areas. It has a prolonged residual effect.

Ant Prevention

• Keep the house clean, free of crumbs or food scraps
• Store food in airtight containers
• Immediately clean up spilled liquids, especially sugary ones
• Seal cracks and crevices where ants can enter
• Keep the external area free of debris and dry leaves
• Cut tree branches that touch the house

Effective ant control requires patience, as the goal is to eliminate the entire colony, not just the visible ants. Baits may take a few days to take effect, but they offer lasting results.
