Bugs on Indoor dwarf citrus trees
I brought my two dwarf Meyer Lemon and one lime trees into my apartment for the winter in Denver. Today I noted the branch end of one lemon tree had a fine silvery gauze (web) draped over the tiny green lemon buds (fruit) and it was swarming w teensy black MOVING spots!!! I presume they are an insect infestation that will damage my three little citrus trees. I sprayed the infested branch with dish soap and water but can’t find a picture online that matches what I see. Can you help? BTW I snapped these photos AFTER spraying the branch w soapy water.

Well, it is an infestation. It isn't an insect, though. It is actually a mite, which is related to a spider. These little guys will completely destroy your trees if not dealt with. Once you see webbing like that, you can consider the infestation severe.
I recommend use a mixture of garlic extract, rosemary oil, clove oil, and a little coconut oil mixed in warm water. This will kill of any living mites. You will have to spray the plants multiple times over a period of about a week.
If left unchecked This will completely destroy your plants very fast. And will spread to other plants in the area.
Thank you SO much for the prompt and helpful reply. Are you able to suggest a ‘recipe’ for this spray ‘remedy’? I’m leaving to buy the garlic extract (can’t just mince a clove?) and rosemary oil as I already have the other two components. Should it be a food grade essential oil (100% pure?) / more pricey?
Thank you very much - I’m spraying all three plants ASAP!!!
