Garden over run by caterpillars and bugs.

Hello I am originally from north west WA but have recently moved to midwest WA. My garden is overrun with 2 types of caterpillar and my citrus trees with leafminer. I have used dust on all vegies but still wake to find whole crops of silverbeet, mint and capsicum leaves looking like skeletons. The caterpillars are large black/brown ugly looking and also small green ones. They are now attacking my succulents, Agave in particular. I have used oil spray on my citrus leaves a few times and not only do they lose all their leaves it seems to burn them and the problem is still there with new growth. All my citrus trees are in very large pots. Could it be that we have ripped out all the existing garden and started from scratch and maybe disturbed the soil which has encouraged all these bugs? I'm talking at least 20 to 50 caterpillars a day. I started off making natural pest control with garlic, chilli, oil and dish detergent but to no avail. Please help.

Answer: Hi Deb,
Most insect’s life cycle is dependent on temperature and weather conditions. This year we have experienced very unusual weather conditions and the moths and butterflies may lay large numbers of eggs. In very warm years there may be more than 1 generation per season.

Yates Success is excellent for the control of a range of caterpillars. It contains spinosad which is a naturally occurring soil microbe that is ingested by the caterpillar.

Citrus leaf miner can be controlled with Pest oil although it should not be used in temperatures over 32 C or when the soil is dry and the plants are stressed. Pest oil causes less damage than white oil in high temperatures.
