In "Teeming with Microbes" I came across the information that nematodes
could control snail and slugs, and more it turns out. Haven't tried it
yet but it is too tempting to pass up.
Anybody have any feed back?
Sorry for the ad.
Beneficial Predatory Nematodes (1 million) - S&H Included
(Steinemema carpocapsae & Heterorhabditis heliothedis)
Control soil-dwelling insects and insect larvae
Heterorhabilitis: Lives inthe top 7" of the soil.
Steinernema: Lives on or near the surface of the soil.
Predatory Nematodes are an effective control for literally hundreds of
pest insects that have a life stage in the soil. This is a partial list
of the more common species "Double-Death" Predator Nematodes are known

As you can see, this is quite a list! This is only the insects known to
have been controlled by "Double-Death" Predatory Nematodes, and many
more probably are controlled by predator nematodes, if they have a life
stage in the soil.
Predatory Nematodes can survive over a wide temperature range (32degrees
90 degrees F.), but are most effective as an insect control at soil
temperatures of 50-85 degrees F. Apply Predatory Nematodes every 4-6
weeks throughout the season when soil temperatures are in this range.
For insects that emerge in Spring and return in the Fall, Springtime and
Fall applications are most effective, timed for when the soil
temperature is about 50-55 degrees F. both times. Use One Million
Predatory Nematodes to treat up to 3,000 square feet of soil surface.
Microscopic Predator Nematodes attack and kill almost any insect that
lives in the soil, even large as a cutworm. Not to be confused with pest
nematodes, Predator Nematodes attack ONLY pest insects, never plants,
and they are harmless to earthworms, too. But if it is an insect, watch
out! So long as an insect spends part of its life cycle resting in the
soil (as many insect pests do) Predatory Nematodes attack by invading
the insect body and then reproducing on what remains, until only a
"shell" is left behind. More nematodes then emerge to repeat the cycle.
Predator Nematodes are so tiny, one million fit on a small 2"sponge.
Each million treats up to 3000 square feet of soil surface. To use,
rinse the sponge(s) in a gallon of water. This gallon can then be
further diluted with as little of as much water as desired, and watered
into the soil.
How do you water them into the soil? It doesn't really matter - you can
water them in with a watering can, spray them in with a pump sprayer
(no, the pressure doesn't hurt them - they go through the nozzle fine),
or even run them through a hose end sprayer or fertilizer injector. The
important things are to use them within 2 hours of mixing (because after
that they start to drown) and release them in the early morning or
evening (because sunlight harms them until they are watered into the
soil). Water them in so they are flushed through the top 2-3 inches of
For most pests, good control has been reached with repeat applications
of nematodes every 4-6 weeks. They will live longest when the soil stays
moist, but not saturated with water. IF you want to store the nematode
"sponges" for a while prior to release, they will keep in the
refrigerator (at 40-50 degrees F.) for up to 2 months. Add a few drops
of water if they seem to be drying out.
Our Predator Nematodes perform better and go farther because they are
raised on a diet of live insects. Some other 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
Predator Nematodes are immediately active and rapidly set up breeding
Although the use of Predator Nematodes is well established for soil
pests, some growers are using them on foliage pests as well. These
gardeners spray nematodes on foliage in the evening and then mist
foliage throughout the night to keep moist conditions favorable to
nematodes. Nematodes actually crawl into the leaf-miner tunnels this way
and have been used against other pests as well. Please let us know your
results if you experiment in the manner and we will pass your
information on. Application: Each package covers 3000sqft, 1500sqft for
fleas. We recommend repeated applications every 4-6 weeks during the
