There are a lot of products and gadgets that are used to keep ants out of our hummingbird feeders. I will share one that LMN from MA let us know about. She will be implementing it and maybe we will hear others doing the same. Here it is, CORNMEAL. It seems that if we feed the ants cornmeal they will die because the cornmeal will swell inside them. It seems a good alternative to using poisons. If anyone else has tried it leave us comments we look forward to your suggestions. Thanks for sharing LMN.
