A 16 ounce BT bottle for home garden routes

Bonide Thuricide BT Concentrate in the 16 ounce size gives gardeners a ready-to-mix concentrate for caterpillar, worm, and moth-control routines. The size feels useful when leaf checks repeat across a home garden through warm active weeks.

Keep it near a dedicated sprayer, measuring cup, waterproof label, gloves, and rinse towel.

Fits vegetables, ornamentals, and bed checks

The product page frames this bottle for home garden use. A gardener can use the label to plan where the spray belongs, then walk the route with attention to leaf tops, undersides, tender new growth, and the plant parts showing feeding.

This approach keeps the spray tied to real garden observations.

Store and mix with care

The 16 ounce bottle should stand upright with the label visible. Keep it away from harvest baskets, seed packets, pet supplies, and plain watering gear.

Mix the amount the route needs, label the sprayer, and rinse each tool after the session.

Good match

This bottle suits gardeners who want a mid-size BT concentrate for recurring caterpillar, worm, and moth-control rounds in a home garden.
