Pest Control Insects

Predatory Nematodes

Predatory Nematodes

ZBG013

Works on soil dwelling pests!
Predatory nematodes attack soft-bodied, slow-moving insect pests. They do not affect earthworms or plants. They are the only biological control that works below the soil surface. Apply in a spray tank or fertilizer injection system when soil temperatures are above 55° F. One package of 1 million nematodes treats up to 3000 square feet. You may store the nematodes in a refrigerator for up to 1 month. Information sheet included in each package.

PLEASE READ: Benefical insects will be shipped immediately when ordered unless prior arrangements have been made with our office. Delayed shipments are not always possible. Additional shipping charges may be applied to delayed shipments.

Beneficial insects will be shipped immediately when ordered unless prior arrangements have been made with our office. Delayed shipments are not always possible. Additional shipping charges may be applied to delayed shipments.

Biological controls have been used for thousands of years and they should be a part of your pest control program. Beneficial insects work by attacking pest insects and thus reducing their numbers. It is important to note that total elimination of pests is not required to grow good crops; it is only necessary to reduce pests below the damage threshold for the crop being grown. When using beneficial insects, it is important to avoid disruptive chemicals. Complete instructions included with each order.

All our beneficial insects are available year-round except the Praying Mantis eggs, which are not available August through December. We recommend releasing beneficial insects outdoors from April through September, based on your local weather conditions. They may be released in your greenhouse anytime.

Sorry, not available to HI or Canada.

Store Refrigerated at 40-50°F Until Use
Microscopic Beneficial Nematodes attack and kill almost any insects that live in the soil — even ones as large as cutworms. Not to be confused with pest nematodes, Beneficial Nematodes attack only pest insects, never plants, and they're harmless to earthworms, too. But if it's an insect, watch out! So long as the insect spends part of its life cycle resting in the soil (as many insect pests do), they attack by actually invading the insects' bodies and then reproducing themselves on the dead insect. When it's completely gone, more nematodes crawl out to repeat the process.

Mixing and Use Instructions
Beneficial Nematodes are so tiny, one million fit on a small 2 inch square sponge. One million nematodes treat up to 3000 square feet of soil surface. To use, rinse the sponge(s) in a gallon of water. This gallon of "nematode concentrate" can then be further diluted with as little or as much more water as desired, and applied to the soil. How do you get them into the soil? It doesn't really matter — you can water them in with a spray can, spray them in with a pump-up sprayer (the pressure doesn't hurt them, and they go through the nozzle fine), or even run them through a fertilizer-injector. The important thing is to use them within 2 hours of mixing, because after that they start to drown. Release them in the early morning or evening, because sunlight harms them until they're watered into the soil. Water them in so they are flushed through the top 2-3 inches of soil.

Why Are These Beneficial Nematodes Different?
Our Beneficial Nematodes perform better and go farther because they have been raised on a diet of live insects. (Some national brands are raised on an artificial diet, and are not nearly as vigorous as our live-reared nematodes.) Stored live in the refrigerator (not dehydrated), our Beneficial Nematodes are immediately active, and rapidly set up breeding and reproducing populations.

Nematodes are the best natural control for soil pests that we've heard of yet. For future study, some growers are using them against foliage pests, by spraying them on at night. In greenhouses, even leaf miners (which tunnel inside the leaves) have been controlled in this manner.

I have never been able to grow any type of root crop. Grubs drilled into radishes, carrots, turnips, etc. This year, I tried beneficial nematodes. Finding a grub in any root has been very rare. I'm ordering another treatment for fall crops.
Organically the best thing I've ever done

Two years ago I had such a bad bug problem that I almost punted gardening as I just wouldn't use chemicals and didn't know what to do. I friend mentioned these microscopic critters that have helped him for a couple of years and said "you can't see them- just trust me and the faith will be rewarded." I went to a local nursery and the gal said the same thing. So I bought 4 "balls" of these for my 7,500 foot garden and surrounding landscape. Dropped in a watering can in mid spring (after the last normal freezing date) and wondered around "watering" the ground. ZERO issues this year and I've turned a few folks onto them for the coming season with the same statement from my original buddy. I'm also going to put some in my 1,000 foot green house just before I start seeding this spring and expect the same results. This is the single best gardening tip I've ever had and I even put them in my mulch piles and considering my lawn this year. Now, anybody know how to get rid of Moles??

My garden became overrun with flea beetles after I harvested a large head of cabbage last summer. They shredded all my kale, collards and other cole crops. I even resorted to bring a hand vacuum-cleaner into the garden and vacuuming them off the plants while waiting for my order of beneficial nematodes to arrive. The nematodes were really easy to apply with a watering can, and I started noticing a smaller flea beetle population within a few days. A week or two later my plants were completely free of flea beetles and the kale, collards, etc., growing undamaged leaves again. That was last summer. This summer, I have no flea beetle problem whatsoever.
they work great
