     * **Imidacloprid:** Highly effective as a systemic root drench to eradicate persistent infestations. However, it is a broad-spectrum insecticide that persists in soil and plant tissue for a year or more; growers recommend selective application, particularly for indoor plants, to avoid harming outdoor pollinators like bees and butterflies. Not available in some areas, such as CA.     * **Imidacloprid:** Highly effective as a systemic root drench to eradicate persistent infestations.

 The community discussion focused on diagnosing and treating severe pest infestations on *Trichocereus* specimens. Initial confusion arose regarding whether the symptoms—including stunted growth and abnormal pup development—were caused by mealybugs, root rot, maggots, or termite larvae. Topic authority Gee Bee identified the culprit as //Hypogeococcus// sp., confirming a mealybug infestation. The discussion detailed various treatment methodologies, ranging from physical removal and alcohol washes to systemic chemical applications like imidacloprid and organic deterrents like nicotine. The community discussion focused on diagnosing and treating severe pest infestations on *Trichocereus* specimens.
