I would ask them about a systemic drench product if spraying has failed and insist on proper inspection prior to them bringing in any new plant materials in the future. good luck. JTV

It has not made an improvement in our situation and the plant company wants to try something else.

Do not click links, open attachments or take action unless you know the contents are safe] Hello, My art museum has an enclosed atrium with tropical plants in the center of the galleries. Unfortunately, during the last replanting, it became infested with mites. Several fairly benign methods have been employed to get rid of them by our plant care company, to no avail. They want to use beneficial insects that eat the mites, specifically Amblysaius andersori. Does anyone have experience with beneficials in museums? Is there any possibility of damage to artwork (paintings, sculpture and works on paper) if these insects were to somehow get out into the galleries? Any advice would be highly appreciated!
