Ant Infestation in Queen Palm: Carpenter Ants vs. Harmless Species

Identifying the Ants

Large ants streaming out during watering are carpenter ants (Camponotus spp.) nesting in the root ball. Tiny ants higher up are likely harmless foragers.

Treatment

• Drench root zone with insecticidal soap or pyrethroid concentrate per label.
• Repeat in 7–10 days to eliminate colony.
• Small ants require no treatment.

Prevention

Keep mulch away from trunk; avoid excessive moisture. Carpenter ants prefer damp, decaying wood but can nest in palm root masses.
