Who doesn't like the thought of having fruit trees that can grow fruit for over 100 years in your backyard? But these plans can be in jeopardy if your trees become infested with ants. Just try one simple but overlooked solution to solve the ant problem: the installation of sticky trunk barriers. Since they prevent the pesky six-legged insects from climbing any higher, they can keep your trees healthy. The ironic part is that ants don't directly damage your trees or make for the fruit.
