According to the product label, Captain Jacks Deadbug Brew Concentrate should be applied when listed pests are present, with repeat applications being made as indicated in the Home Gardens section of the label. As application intervals for olive trees are not specified on the label, you should either contact your local extension office for treatment guidance, or you may contact the manufacturer directly with product questions here.
