I have tried spraying them with a general garden insecticide, but it doesn't seem to be helping. Any idea what the bugs are or how to get them to go away?
If it helps, I'm in Houston, Texas.
Thank you!

kumquats are subject to mealybug infestations. Dooryard and orchard trees may be attacked by most of the common citrus pests. They are highly resistant or even immune to citrus canker. The following diseases are recorded by the Florida Department of Agriculture as observed on kumquats: scab (Elsinoë fawcetti and its conidial stage, Sphaceloma fawcetti; algal leaf spot, or green scurf (Cephaleuros virescens); greasy spot (Cercospora citri-grisea); anthracnose (Colletotrichum gloeosporioides); fruit rot, melanose (Diaporthe citri); stem-end rot and gummosis (Physalospora rhodina).
