Years ago, there was plenty of open, natural veld surrounding our towns and it was rich in wildlife. As towns expanded the only remaining natural veld and wildlife shrank to occur only in patches between town, factories and farm land.
All gardens have problem animals that damage plants.
Although pesticides will kill them, they may also kill harmless animals such as birds, spiders, lizards and other creatures that are helpful to gardeners. There are many ways of getting rid of pests without killing helpful animals or harming your garden. Allow to stand for two days. Spray the diluted mixture on the leaves of affected plants. This spray will chase pests away without killing them.
