White butterfly are notoriously difficult to get rid of. Here are a few suggestions from Tod and Awapuni customers.
1 Hose off as many of the eggs, caterpillars and butterflies as you can from the plants. Then spray the affected plants with neem oil.
2 Cover the plants or garden completely with white netting from your local garden centre - the kind that covers but doesn't shade, which will also protect against birds.
3 Try a chilli and garlic spray to repel the white butterfly.
4 Plant French marigold (tagetes patula) and spray plants with seaweed spray.
5 Plant rhubarb or use a rhubarb and garlic spray
6 Use a robo can in hot houses
7 Lastly, send out an army of children with butterfly nets – if necessary pay 10 cents per butterfly!
