We took the girls out for their walk tonight. We just arrived in our park two days ago. We noticed ants on us the other night after we went down to the grassy patch. It rained really hard this evening...
The primary ingredient in ant venom is formic acid, so baking soda paste should be very effective. I think if she's not fussing with the bites, I'd leave them alone lest you irritate 'em.
