Garden pest control continues evolving β spotted lanternfly has expanded into new states, chlorantraniliprole is replacing neonicotinoids for grub control, and biological controls like beneficial nematodes and Beauveria bassiana are gaining mainstream adoption. Here's what's changed and what still works.
Spotted lanternfly range expansion: Now confirmed in 17+ states and expanding westward. Homeowners in newly affected areas need to learn identification, reporting, and the circle trap + systemic treatment approach for tree of heaven. Our spotted lanternfly management guide covers the current best practices.
Pollinator-safe grub control: Chlorantraniliprole (Acelepryn/GrubEx) has largely replaced imidacloprid for lawn grub prevention. It controls Japanese beetle and white grubs with dramatically lower pollinator toxicity. Apply JuneβJuly for preventive control.
Biological controls going mainstream: Beneficial nematodes for grub and flea control, Beauveria bassiana for whitefly and aphid management, and Metarhizium for tick control in yards are all commercially available and increasingly reliable.
Spinosad: Still the best organic caterpillar, thrips, and leaf miner control. OMRI-certified, low mammalian toxicity, highly effective. Apply in evening to minimize pollinator contact.
Bt kurstaki (DiPel, Thuricide): Caterpillar-specific, zero impact on beneficial insects. The gold standard for tomato hornworm, cabbage looper, and bagworm control.
Neem oil: Broad-spectrum organic control for aphids, whiteflies, spider mites, and mealybugs. Apply in early morning or evening β never in direct sun (phytotoxicity risk).
Insecticidal soap: Contact kill for soft-bodied insects. Must coat the pest directly. No residual β but also no residue to harm beneficials after drying.
Row covers: The most effective non-chemical protection for vegetable seedlings against flea beetles, cucumber beetles, and cabbage moths. Physical barriers that require zero chemicals.
