Natural Habitat

Nests in soil, often under rocks, logs, or pavement; frequently enters homes during swarming events.

Diet & Feeding

Feeds primarily on 'honeydew' secreted by aphids and mealybugs; also scavenges for sweets.

Behavior Patterns

Nocturnal and subterranean; queens and males swarm in fall or spring for mating flights. Known for emitting a citrus-like scent when crushed.

Risks & Benefits

Generally considered a nuisance pest rather than a threat; they do not sting or cause structural damage, but their presence can indicate soil nesting near foundations.
