Citrus Leafminer

The Citrus Leafminer (Phyllocnitis citrella) has been very active on the new growth of Santa Barbara citrus trees this year. Their larvae tunnel mines inside the leaves distorting growth. The adult form can fly between trees and travel on wind currents.

Mature trees may withstand an invasion but the growth of young trees may be retarded with heavy prolonged infestation.


  1. Where possible infested areas may simply be cut out.
  2. Organic spray Spinosad is labeled for use on Citrus leafminer. It is a naturally occurring compound produced by a bacterium and is translocated into leaves.
  3. Parasitic Wasps are Leafminers’ natural enemies. Populations will increase and ultimately provide biological control.

We have made the hard decision to close on Friday, April 3, 2020 to help protect our families and yours, and to help enforce the stay at home order. We will be back in the near future to serve you!

We have suspended phone and email/online orders effective immediately, so that we can focus on filling orders already received. We apologize for the inconvenience.
