Seeing ants inside your house lately? As Californians enjoy the long-awaited rainfall, something linked to rain is not as welcome: ants.

It's normally found living in the landscape in shallow nests, and might even be living just outside your building. When rainy weather floods their nest, Argentine ants may use your home or...
