Bathroom sink ant infestation
I recently moved in a home in Southern California. I've noticed a few ants in various places throughout our home so went to Home Depot and purchased ant killer and a gallon sprayer and treated all along the perimeter of outside the house and inside the garage. This morning I woke up to a few ants coming from the two upstairs bathroom sinks so I got the spray, and treated under the cabinets and along the pipes. The number of ants in the master bathroom sink went from 3-4 to hundreds within 10 minutes. Is this an infestation in the pipes? Pest control can not come out until tomorrow or Thursday...is there anything I can do in the meantime? My house is very clean, no food or sugary substances anywhere out. I don't know why this is happening.
