Key to Identifying Common Household Ants
|
|
Odorous house ant trails are common along sidewalks |
Colony propagation Colonies begin in the spring and summer months by budding, which occurs when a mated queen crawls out of the nest with some workers to establish a new colony. Occasional late spring swarms, or reproductive flights, may occur. Colonies have multiple queens. Odorous house ants invade homes most likely during rainy weather since their natural food supply (honeydew from insects) is washed from vegetation. Ants can be active all year round in homes, but outdoors they overwinter as workers or larvae until temperatures warm in March, when they begin to forage once more. |
