Our Beneficial Nematodes arrive ready-to-use. Just add to water!
NemaSeek Hb (Heterorhabditis bacteriophora) Beneficial Nematodes seek out pests living in the soil. Beneficial Nematodes are live microscopic organisms (non-segmented round worms) that occur naturally in soil throughout the world. They are parasitic to insect pests that typically have a developing (larval or pupal) stage of life in the soil; however, they have been known to also parasitize above ground stages of adults, nymphs and larvae. They are completely safe to use and will not affect mammals, aquatic life, birds, reptiles or amphibians. After application, the nematodes immediately get to work. Upon finding a pest, they can enter it through various body openings or directly through the body wall. Once inside, it is not the nematode that actually kills the pest, but the toxic bacteria inside the nematode's gut that is the real weapon - symbiotic bacteria, that when released.
These nematodes are adapted to all climates but should not be applied until after the last threat of frost. Prefers a soil temperature of 65° F.

How long can nematodes be kept before use?
Beneficial Nematodes should be used as soon as possible. Because they are live organisms, it is best to store them for no longer than 2 weeks in a refrigerator that is between 37° and 42° F.
How are nematodes applied?
The solution can be applied using a watering can, hose end sprayer, backpack or pump sprayer or through irrigation or misting systems. Please see the instructions for the Chameleon Adaptable Hose End Sprayer for hose end sprayer directions.
When should they be released?
Release early in the morning or predusk when temperatures are cooler and the sun is not so bright.
Should the soil be moist after the nematode application?
The soil should be moist at time of application and lightly watered immediately after application. After application, regular watering of the treated area will provide sufficient moisture. Generally speaking, water every 3-4 days if rainfall does not occur.
What's the Application Rate?
It is best to make at least two applications, separated by 7-10 days in order to stagger the life cycles of the nematodes and to assure complete coverage. In cases of severe infestations, applications should be made every 7-10 days or until infestation subsides.
|Package Size||Quantity ||Treatment Area |
|1/2 Garden Backyard Size ||5 million ||1,600 sq. ft. |
|Garden Size ||10 million ||3,200 sq. ft. |
|Farm Size ||50 million ||1 Acre |
|Small Ranch Size||250 million||5 Acres |
|Large Ranch Size ||500 million||10 Acres |
How long does it take to see results?
In general 3-7 days for caterpillars such as cutworms, armyworms, sod sebworms. For grubs and weevils such as Japanese beetle, black vine weevil and billbugs feeding stops within 3 days with maximum control occurring over 2-4 weeks. Nematodes disintegrate the pests from the inside out. You will not see dead insect bodies as you would with a chemical knockdown.
How often should nematodes be applied?
Nematodes are recommended for use whenever larvae or grubs are present. Generally, this is during the spring and fall months. Because larvae feed on plant roots, beneath the soil surface, severe damage can be done before realizing there is a problem. Look for signs of an adult insect, such as leaf-notching. If adult insects are present, their eggs will be hatching soon. Keep in mind, one application may not eradicate a population of insects that has become established over a period of years.
Will nematodes live through the winter?
In general, harsh winter weather in most parts of the country almost guarantees a significant decline in the population of the nematodes. In most cases, nematodes (just like insects) will become dormant during cold weather. Any survivors would be few in number to provide adequate insect control. If your insect pest returns the following year, another application may be necessary.
When nematodes are applied to one area will they move to other areas?
Nematodes, due to their microscopic nature have limited range of movement. Generally NemAttack, our formulations of Steinernema will stay where you put them, but NemaSeek (Heterorhabditis) will continue moving through the soil until they find a pest to infect.

For 15 years I tried all of the traditional grub treatments for my lawn. They all failed and the mole tracks were incredible. Five years ago I tried Arbico's NeamSeek nematodes with much success. I have continued the nematode treatments three times a year-no mole tracks. It also helps with the beetle,flea, and tick populations on my grassy acre.
