You could try a bitumen band to stop crawling insects, but don't put bitumen directly on to the bark. But flies can only be stopped by spraying or netting, though there are some plants, such as lavender, which act as a deterent.
If brains were made of dynamite, I wouldn't have enough to blow my nose.

Some insects are needed for pollination of flowering plants. Some insects like ladybeetles control other insects like aphids. Spiders and their webs catch flying insects. So not all creepie-crawlies are bad.

You can get pheromone-baited traps, which will be species-specific.

For fruit trees, you can try covering the fruit with paper bags - labour-intensive, but not poisonous to the insects.

If there is any truth of Lavender, and the flowering time coincide(if that's the repellent), why not get "small plastic pots of Lavendar" and rope them all the way up the trunk?
All i know for less dangerous chemicals is the fruit farms sprayed a substance made by fuel companies called "white oil" half a century back(i think Shell Co. made it).
