Yeah – a slippery slope to nowhere! At least for the ants that love to take over your hummingbird feeder. Ants are attracted to the nectar in the feeder and, being the highly social bugs that they are, will quickly “tell” all their little friends when they’ve found this seemingly never-ending source of food. Foil them by smearing the string or wire holding the feeder with petroleum jelly. Ants find it nearly impossible to cross a barrier with this sticky substance.
