Greenhouse Pests

If growing in the greenhouse, tender, new growth may attract common greenhouse pests such as aphids, thrips and the greenhouse whitefly. Overwatered plants may also attract fungus gnats. Cutworms are another possible problem.

Outdoor Pests

Deer, rabbit or squirrels rarely disturb the primrose, but it may be subject to damage from virus, bacteria and fungus. Disease is commonly spread by insects. Treat disease immediately upon discovery. Before they spread.

Nighttime Damage

Slugs and snails may collect near the base of primrose's basal rosette. Since these pests feed at night, look for them with a flashlight. Cutworms may also eat the primrose. Hand picking the pests may be all that is required. Attract beneficial insects to the area by planting marigolds, nasturtium and fragrant herbs. Bacillus thuringiensis, an organic biological control, is an alternative to chemical treatments.
