FAQ
Frequently Asked Questions
Mealybugs are a specific type of scale insect (in the family Pseudococcidae). All mealybugs are scale insects, but not all scale insects are mealybugs.
Yes, a severe, untreated infestation can weaken a plant significantly, stunt its growth, and potentially kill it, especially young or stressed plants.
They spread slowly by crawling, but can be moved quickly over long distances by wind, on clothing, tools, or through the trade of infested plants.
For light infestations, physical removal with a cotton swab dipped in rubbing alcohol is effective. For heavier infestations, insecticidal soaps or horticultural oils are commonly recommended.
