We are RIDDLED with fires ants. I am looking for suggestions for control around the pool. I'm quite certain they are nested under the concrete deck since I've now seen them coming up from under the mounted rails at the steps as well as a small crack where the swim out steps are installed in the deep end. I don't broadcast ant poison in the yard since we are on 26 arcres with a two acre pond where runoff goes (didn't want to pollute) the pond. We try to just treat individual mounds when the arise but what can safely be done in and around the concrete decking? BTW I have an allergy to at least one of the three species that live here in SC. I want to keep the pool area as safe as possible so I don't end up having a full reaction to an ant bite or worse in the hospital from several ( found a "raft" of them today clinging to a piece of debris) and don't want to poison the pool. Any suggestions?
