How are Nematodes Shipped?
REFRIGERATE UPON ARRIVAL. Remove nematode bag(s) from insulated shipping container or packaging and place in refrigerator until ready to use. Nematodes are shipped in an easily dissolved formulation that you mix with water.
 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 RL Flo-Master 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?
The Garden Sizes of NemAttack™ and NemaSeek™ contain 10 million nematodes and will effectively treat approximately 3,200 sq. ft. The Farm Sizes contain 50 million nematodes and will effectively treat 1/2 to 1 full acre of treatable surface depending upon level of infestation. The Ranch Sizes contain 500 million nematodes and will treat approximately 10 acres. 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.
How Long Can Nematodes Be Kept Before Use?
Beneficial nematodes can be stored in a refrigerator for up to two months (do not freeze!). The best way to store unused portions is to place them in a large shallow storage container and cover with about ½ inch of water. This is to ensure that they do not dry out and that the maximum area is exposed to the air so they can breathe.
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.
