Leaf bugs
How to get rid of leaf bugs
Leaf bugs are not usually a problem on mature plants, but should be controlled on young plants. The symptoms are irregularly placed round holes of varying sizes in the leaves. These are caused by sucking on leaves or fruit. Some species of leaf bugs release toxins that can cause twisted and bent plant parts.
Affected plants
- Fruit
- Beans
- Potatoes
- Cabbage
- Ornamental plants (hibiscus, roses, ...)
Treatment
Collecting them (especially in small gardens) has proved to be the best method. This is quite simple as they will play dead when threatened and drop to the ground where they can be easily collected. Choose an early part of the day when the bugs are still sluggish. You can then cover the infested plants with close-meshed vegetable netting to protect them from re-infestation.
If this doesn't help, you can make soapsuds by dissolving 20-30g of natural soap in a litre of water. Use this to spray all affected plants 2-3 times a day. CAUTION: Plants with soft, delicate leaves (lettuce, leafy vegetables) will not tolerate soap.
Further information
Leaf bugs are most common during hot, dry periods in the summer. As a preventative measure, mulching and watering your plants will usually help. In spring, you can check your plants regularly for these pests to prevent them from spreading. Beneficial insects such as birds and toads can also keep leafhoppers at bay.
