If you are suddenly seeing ants in your kitchen, bathroom, or along baseboards, you are not alone. Many homeowners throughout the East Bay experience a sharp increase in ant activity during certain times of the year. What feels sudden is usually the result of environmental changes, colony growth, or seasonal patterns that drive ants indoors.
Rainfall in the Bay Area often brings relief from dry conditions, but it also triggers a noticeable increase in pest activity. Homeowners and business owners frequently report ants, spiders, rodents, and other pests appearing seemingly overnight after a storm. This surge is not random. Rain fundamentally changes pest environments, forcing insects and animals to adapt quickly, and homes often become the most attractive refuge available. Understanding why pests spike after rain can help Bay Area residents recognize early warning signs and take action before a minor issue becomes a full infestation.
