Real small ants are in the cat's bowl. The food is dry food, not something that is obviously attractive to pests. A pest control guy comes four times a year. In fact, this latest infestation occurred an hour after the technician left.
Here's the rub: I can't see where the ants are gaining access. They just show-up at the bowl. There's no line of ants carrying food back to the nest, either in small cracks or toward a door. Any explanations? Thanks.
