FOR USE

Apply MONTEREY B.t. RTU when worms or caterpillars are first noticed, then repeat at five (5) to seven (7) day intervals while they are active. Apply more frequently to control heavy infestations. Apply thoroughly to top and bottom of foliage. Reapply after heavy rains.

MONTEREY B.t. RTU must be eaten by worms or caterpillars to be effective. After ingesting the insecticide, they immediately stop feeding, though they may otherwise appear to be unaffected for several days. Best results are obtained by treatments when worms are small; they must be actively feeding on treated, exposed foliage. You may apply MONTEREY B.t. RTU up to and on the day of harvest.

FRUITS AND VEGETABLES:

Spray all plant foliage. Apply at first sign of infestation and repeat at weekly intervals when needed to insects in the fruit and vegetable garden:

  • Cabbage Looper, Armyworms, Hornworms, and other Lepidopteran (moth) pests on broccoli, cauliflower, collards, kale, mustard greens, turnip greens, cabbage, celery, lettuce, melons, and tomatoes.

SHADE TREES & ORNAMENTALS:

Spray at first sign of infestation and repeat at weekly intervals when needed to maintain control. Apply to thoroughly cover all foliage surfaces of shade trees and ornamentals for control of the following leaf-feeding worms:

  • Bagworm, Spring Cankerworm, Fall Cankerworm, Gypsy Moth*, Tent Caterpillar, Elm Spanworm, Fall Webworm

*Apply when buds swell, but before leaves are fully open. If eggs hatch over a long period of time or if reinfestation occurs, spray about 14 days after first appearance.

    Monterey. B.t. RTU

    By Carol on 08/30/2015

    We had tried many products to kill the caterpillars on our bougainvillea but to no avail. This product worked beautifully. It killed all the caterpillars the first time we used it. We give it a five star.

    Great for my Papaya trees

    By Jerome on 09/28/2018

    A couple of years ago I planted some Papaya trees. They got infested with some hornworm. I picked them off, but they kept coming back. I purchased the Monterey B.t RTU and it got rid of them. Use it every year and it works great.

    It works

    By Ron on 06/14/2019

    For years I have dealt with leaf roller caterpillars on my Canna plants. I have tried other options to control them, but to no avail. This product was the first one to work.

Questions & Answers

Have a question about this product?
  
Q
Can Monterey B.t. RTU be used on my Meyer Lemon Tree for worm/caterpillar infestation?
A

Monterey B.t. RTU is not labeled for citrus fruit, including lemons.

We would recommend using Natural Guard Spinosad Landscape and Garden Insecticide instead. It is labeled for use on lemons and will kill caterpillars on the tree. One bottle will treat approximately 5300 square feet.
