Safer® Brand Caterpillar Killer II Concentrate With B.T. - How It Works

Safer® Brand Caterpillar Killer Concentrate uses a naturally occurring bacterium to kill and control caterpillars and other leaf-eating worms. The caterpillars and worms that are damaging your plants will stop feeding immediately after ingesting the bacterium, which is known scientifically as Bacillus Thuringiensis var. Kurstaki (B.t. for short). Plus, when Caterpillar Killer is used as directed, it has no effect on birds, earthworms, or beneficial insects such as honeybees and ladybugs.

This economical concentrate is easy to mix into a ready-to-use solution. And, because Caterpillar Killer is OMRI Listed® and compliant for use in organic gardening, you know that you’re controlling leaf-chomping caterpillars in a way that fits into your organic garden plan.

Identify Damage

Eliminate a variety of caterpillar & worm species. Visible damage from each will be different. Tomato hornworms eat entire leaves, stems, and the fruit of the plant, causing it to look like someone took a bite. Other worms, like tent caterpillars & fall webworms, form webs on trees & shrubs resembling white bags made of spiderwebs. Below these “tents” are dozens of caterpillars eating the leaves.

B.T. To the Rescue

Bacillus thuringiensis var. kurstaki is a naturally occurring bacterium that kills certain leaf-eating worms and caterpillars. Simply spray Caterpillar Killer onto trees, shrubs and vegetables so that worms and caterpillars eat the treated vegetation.

The bacterium includes a toxin that stops them from feeding or causing more damage to your plants. Within a few days, effected caterpillars and worms will die of malnutrition. Safer® Brand Caterpillar Killer can be used until the day of harvest, so you can protect your plants through their entire growth cycle.

Won't Harm Beneficial Insects When Used as Directed

Safer® Brand Caterpillar Killer controls and eliminates a variety of destructive caterpillars and worms. When used as directed, this treatment won’t harm birds, earthworms and beneficial insects, such as honeybees and ladybugs. These beneficial organisms are important to our ecosystem, and their survival is vital to the continued production of nutrient rich soil and the natural pollination process of flowers, fruits and vegetables.

How to Use

How to Use Caterpillar Killer

Mix caterpillar killer as directed to achieve desired amount of solution. Once Caterpillar Killer is sprayed onto plants and the treated vegetation is ingested by caterpillars and worms, feeding and damage will stop immediately. Keep in mind that more caterpillar eggs may hatch, so it’s best to monitor the area for newly hatched pests even after treatment. If more caterpillars are noticed, you may need to repeat the treatment again after 5-7 days. It’s recommended to apply Caterpillar Killer late in the afternoon or on cloudy days as B.t. can breakdown in excessive sunlight.

An Economical, Easy-to-Mix Solution

This 16 oz bottle contains a concentrated solution that creates over 250 times that amount in usable caterpillar-killing solution. Simply mix a small amount of concentrate with water as directed until you reach the desired amount of solution. Store any unmixed concentrate in a cool place for later use. One 16 oz bottle of concentrate makes up to 32 gallons of solution and protects over 10,000 square feet of plantings.
