Exclusion Barriers - Netting Your Fruit Trees

Exclusion barriers - netting your fruit trees, covering your fruit

In addition to baiting, gardeners could consider covering fruit trees with very fine netting such as mosquito netting or place paper bags over fruit.

What it is

Exclusion is a preventative method that uses physical barriers to stop female adult fruit flies from reaching your fruit and vegetables. This method forces female flies looking to lay eggs in your crop to search elsewhere for a suitable host. Typical barriers that can be used around the home garden are nets, bags and sleeves.


When to do it

Exclusion barriers should be applied as early as possible during the growing season. This can mean as early as petal drop, indicating that pollination has occurred, or as fruit are just developing. Placing exclusion products on the plant at this time will protect your produce, since fruit flies tend to target fruit and vegetables that are maturing or ripe. If you suspect that your produce has already been stung, then remove it before netting or bagging. Note that self pollinated crops can be covered anytime before fruit matures or ripens.

Bags and sleeves

Bags and sleeves are generally a little more easily made because of the size required and materials used to make them. For exclusion products such as bags, some gardeners have been known to use: brown paper lunch bags (which may get soggy when it rains); wax paper bags that are used for keeping mushrooms in; and mosquito netting cut and sewn to size. Sleeves can be made from materials such as mosquito netting, fly screen and gauze curtain material, also cut and sewn to desired size. Both bags and sleeves can be secured to the tree or plant with string, clothes pegs or tie wire.

Remove barriers

At the end of the growing season, remove any barriers that you have used from the garden and store away for next season. Repair or discard any barriers that have been damaged.
