Abandoned trees in backyards can be a risk to nearby commercial citrus groves. This is because abandoned trees may have psyllids that are not being controlled. These psyllids can spread to nearby commercial plantings and infect them with citrus greening disease.

It takes just one infected psyllid to transmit the disease, so it’s important for homeowners to watch for and control pests in their trees, too.
