Weaver ants! Friend or foe?
I woke up today and got a shock when I realized my garden was being swarmed by red weaver ants. I had noticed a few of them over the past weeks, but had always assumed they were just 'strays'. Now they're building their leaf-nests all over my morning glories and hibiscus plants. I did read somewhere that some gardeners use them as a form of natural pest control, but is it worth it to endure painful bites and unslightly bunches of leaves? What are the most effective methods of control that will have a minimal impact on my organic garden?
