Live insects from Tip Top Bio Are Expedited To Ensure Your Insects Arrive Quickly & Safely.

Encarsia are used to control several species of whitefly indoors and outdoors. They can control silverleaf/sweet potato whitefly with increased quantity releases. Adults are very small black insects about 1/20 inch long. They do not bite or sting and go virtually unnoticed. Encarsia Larva develop inside the immature whitefly scale, which darken and turn black.

Encarsia work best if temperatures are over 68°F and relative humidity is 50-70%. When daytime highs are regularly below 64°F Encarsia activity decreases making them less effective. Like with most beneficial insects it is best to begin releasing Encarsia when Whitefly infestation is light.

Other whitefly predators such as; Delphastus catalinae (beetle) and Eretmocerus eremicus will co-exist with Encarsia formosa and help expedite control.

Encarsia pupa are sold on hanging cards. We recommend to hang the cards on lower leaves in the shade. Avoid getting the hanging cards wet when watering.

If necessary, the Encarsia can be stored for up to 2 weeks at 40°-50°F, however immediate release is best.
