Can you tell me the best way to keep bugs off

Today i just learned to know that there is one way of getting rid of bugs which i din't think of before. First find a insect hormone which will attract them. Paste it on a polysterine board. Place it near the tree. This is the second best way i could think of. The best way, for me is, setting up a fence to totally cut them off from the bug. Coz this does not involve killing of those little creature. But this is costly for you i think. The number 3 solution is to use bio control (keep predators). The worst way would be using pesticide, whihch i really won't recommend you for that.

How abouta smoke machine. something with smoke might work. Give it a try.

What sort of bugs are you finding? Its normal to have a wide range of creepy crawlies living on fruit trees, a lot of them are useful pollinators or pest control of their own. Its just a few types you don't want and that cause damage. What type of fruit and what specis of bug do you have, and what damage do they seem to be causing? Might help us make useful suggestions.
