Safer Brand BioNEEM Insecticide and Repellent

Size Price

This unique insecticide and insect repellent controls over 30 common insect pests!

The Safer® Brand BioNEEM® insecticide and repellent concentrate works as a powerful insect killer and repellent. This product is formulated with azadirachtin, a natural Insect Growth Regulator extracted from the Neem seed. BioNEEM® effectiveness is based on several modes of action. It disrupts insects’ delicate hormonal balance so they die before they molt to the next life stage. It also suppresses some insects’ desire to feed and repels many insects in areas that have been sprayed. These different modes of action result in broad spectrum control of the majority of insects that harm your yard and garden. BIONEEM® kills or repels a broad assortment of insect pests, and spares many beneficial insects such as honey bees and lady bugs that prey on undesirable insects. Without beneficial insects to control pest populations, plants are even more vulnerable to new infestations.

BioNEEM® is OMRI Listed® and compliant for use in organic gardening.

Use a neem oil solution such as BioNEEM® on trees, shrubs, ornamentals and flowers. Water to concentrate ratios may vary per the type of plant being treated.

Remember, when using Neem oil products, there is greater risk of phototoxicity (burning).  Avoid using sulfur based fungicides within the active period (5-7 days) of the BioNEEM® application. These two products combined, greatly increase the risk of plant burn.

While Safer® Brand BioNEEM® is a contact killer, several applications of the neem oil may be needed for full control.  As a general rule, much like watering, do not use neem oil in the peak of the day or when temperatures exceed 90 degrees F to avoid wilting or browning of the leaves.

It breaks down into it’s natural elements within 7-10 days, leaving no residual impact on the environment.

Directions for Use:

Shake well before using. Use spray solutions within 8 hours of mixing for maximum effectiveness. Do not store diluted spray solution for later use. Not for use in food handling areas.

Since BioNEEM® interferes with insect growth function, it is most effective when applied 2-3 times at 7-10 day intervals. Application directly onto the target pest will increase efficacy. Time applications for early to mid morning or in the late afternoon.

Note:  Do not add other chemicals to BioNEEM® solutions. Do not apply to wilted, stressed, or newly transplanted materials prior to root development.

Safer Brand Caterpillar Killer II with B.T. Concentrate

Size Price
16oz $15.95


Safer® Brand Caterpillar Killer with B.t. (bacillus thuringiensis var. Kurstaki) is an effective organic solution for caterpillar and worm control.  Caterpillar Killer kills worms and caterpillar stage insects, but has no effect on birds, earthworms, or beneficial insects, such as honeybees and ladybugs, when used as directed. Worms and caterpillars eat treated foliage then immediately stop feeding and damaging plants.

Effective for: Cabbage looper, imported cabbage worm, tomato hornworm, bagworm, spring cankerworm, fall cankerworm, gypsy moth, tent caterpillar, elm spanworm, fall webworm.

How it Works

  • When the B.t. is ingested by the worm, it works as a gut rot poison that makes the worm stop feeding. The caterpillar or worm will stop feeding immediately and die within days of malnutrition. This caterpillar killer will keep your lawn and organic garden, free from caterpillars all year long.
  • It is recommended that this product be applied late in the afternoon or on cloudy days since B.t. breaks down in the sunlight.
  • Carefully read and follow all directions on the product’s label. B.t. is very specific and only works on caterpillars and leaf feeding worms. It is recommended with any pesticide to test plants for sensitivity to the product. Spray a small section of the plant in an inconspicuous area and wait 24 hours before full coverage.

Application Rates:

Apply Safer® Brand Caterpillar Killer when pests are first noticed and repeat every 5-7 days or as necessary. Caterpillar egg hatching can occur over an extended period of time. Monitor treated areas for the presence of newly hatched pests and retreat if necessary. Thorough leaf coverage is necessary for effective control. After ingesting a treated portion of the leaf, caterpillars stop feeding in a few hours and death occurs in a few days.
