Safer's BTK Insecticide - 100 ML

Safer's BTK Insecticide is a biological insecticide concentrate for caterpillar control, designed to protect garden plants from destructive caterpillar activity. It’s a targeted caterpillar control insecticide for gardeners who want a focused solution for leaf-damaging larvae without broad, catch-all pest claims.

This btk insecticide is built around Bacillus thuringiensis subsp. kurstaki, strain ABTS-51, a well-known btk biological insecticide used for selective caterpillar management. Safer's BTK Insecticide is described as highly specific to some kinds of caterpillars, making it a practical choice when the problem is clearly caterpillars rather than a mixed pest situation. It targets common culprits such as cabbage worm, tomato hornworm, tent caterpillars, gypsy moth caterpillars, and leafrollers, along with other caterpillar pests that chew foliage and reduce plant vigor. It is not positioned as an option for aphids, so it’s best reserved for clearly identified caterpillar pressure.

A key benefit of this btk biological insecticide is how quickly it interrupts damage after caterpillars consume treated leaf tissue. Once exposure occurs, caterpillars stop eating within hours, and control typically follows within a few days, helping limit ongoing leaf loss. For timing expectations, Safer's BTK Insecticide is described as most effective when caterpillars are small and young, aligning with early detection and fast response. It also does not target adult moths, which helps set clear expectations for what this caterpillar killer concentrate is designed to address.

Safer's BTK Insecticide is suitable for use on vegetables, fruit, trees, and ornamentals, making it a versatile garden insect control concentrate for mixed plantings. This is a good fit for home gardeners and greenhouse growers who want a btk insecticide focused on cabbage worm and tomato hornworm scenarios, leafroller damage, and tent caterpillar outbreaks, with an active ingredient identified as Bacillus thuringiensis subsp. kurstaki, strain ABTS-51.
