Bonide Systemic Houseplant Insect Control 8oz
by Bonide
Bonide's Systemic Houseplant Insect Control granules contain imidacloprid, a systemic neonicotinoid insecticide that is absorbed by plant roots and transported throughout the entire plant structure. This means insects are killed through ingestion when they feed on treated foliage — including pests on the undersides of leaves and inside growing tips where sprays can't reach. One 8-ounce application protects houseplants for up to 8 weeks with no visible residue and virtually no odor, making it especially effective against mealybugs, scale, and aphids.

What We Love
- Systemic action reaches pests that sprays miss — hidden in growing tips and leaf nodes
- 8-week protection window from a single application
- No visible residue and virtually odorless
- Highly effective against mealybugs and scale — notoriously difficult to control
Worth Knowing
- Imidacloprid is toxic to bees and pollinators — do not use on flowering plants that are pollinator-visited
- Not appropriate for edible crops indoors
"For houseplant mealybug and scale infestations — the two pests that most commonly resist repeated spray treatments — systemic granules are the most reliable solution available. The neonicotinoid chemistry is controversial due to pollinator toxicity, but for indoor non-flowering ornamental plants that never interact with bees, the risk profile is minimal. Apply at potting, water in thoroughly, and reapply every 8 weeks during the growing season for season-long protection."
