Description

Keep your roses safe from hungry caterpillars with Monterey BT Biological Insecticide! Caterpillars can be a major garden pest, chewing through leaves and damaging new growth, which can weaken your plants over time.

This product uses natural bacteria that specifically target caterpillars, stopping them from feeding and eliminating them quickly—without harming people, pets, or beneficial insects. Because it only activates inside a caterpillar’s digestive system, it’s a safe and effective way to reduce damage and keep your roses healthier all season long. Simply apply as directed for best results!
