Yates PestOil Insect Control Spray

For Citrus Leaf Miner, it has to be the most useless product on the market – For the Yates Pest Oil Insect Control Spray Concentrate I was extremely diligent when mixing the correct ratio exactly as indicated on the cannister. The mixture ratio for Citrus Leaf miner is given as follows:  5ml / 1ltr. of water. It does not work and never did. I upped the recommended dosage to 10ml / 1ltr. of water. Citrus Leaf Miners seemed to eat this stuff for breakfast, lunch and dinner as no matter how methodical I applied this under and above the leaves, they thrived. I am in WA where the Citrus Leaf Miner is a huge problem so one can find Yates Pest Oil Insect Control in premixed form at most of the big supermarket stores like Big W, Woolworths or Coles. If one wants the concentrate, one would have to shop at say a Bunnings or Mitre 10. I have tried both forms, without success. My next and last attempt to address the Citrus Leaf Miner problem on my citrus trees was to increase the frequency of application. Instead of eliminating Leaf Miners they multiplied. It was good money wasted time after time until the realization in that it was by far one of the most useless products I have ever encountered. Avoid at all costs.
