Meyer Lemon Tree Pest
Hi, Well I'm wondering if your plants have Scale. Scale are not eggs, but flat, fingernail-like insects that love to infect plants like citrus, schefflera and ficus. The soapy water shouldn't hurt your tree, but you need to be careful because some soaps can cause more problems. Plus, soap won't stop scale. If you only have a few scale, then take a Q-tip with rubbing alcohol and rub each one to kill it. Otherwise, get a general-purpose systemic insecticide that says it will kill scale on the label. These bugs are a nightmare to get rid of and in the past, I've often just given up and thrown scale-infested plants away.
