Beneficial Nematodes are applied like any conventional spray application via a back-pack sprayer, boom spray, watering can or venturi hose end sprayer. No, for example fungus gnat nematodes can be applied to a single plant pot with a minimal fungus gnat infestation to stamp it out early. Q - I have been keeping the compost quite dry to try and get rid of the gnats, will this be ok for the nematodes? And it is even better when we can use a natural biological method of control, instead of always resorting to the insecticidal soap.

For a quick timeline: I had a few gnats flying around my room, which went forth and multiplied, so I had more gnats flying around. litre of water for the 5 million pack concentrate, and add at least 1 litre of water for the 10 million pack concentrate. Adults measure 1/8 to 1/10 inches long (about the size of a common gnat) and they are distinguished from another greenhouse pest, the shore fly, by their long antennae. If new plant material is introduced into a greenhouse area, or if yellow sticky card monitoring indicates that fungus gnat populations exceed action thresholds, conventional insecticides can be used to quickly reduce adult populations.The nematodes kill the vine weevil larvae, which do the most damage to the plant by eating the roots. Multiplying nematode-bacterium complex causes septicemia and kills the host usually within 48 h after infection. The nematodes kill the fungus gnat larvae, which are hiding in the soil of your plants and hatching into more gnats. Place the stand holder into the soil in a pot, keeping the sticky card a few centimetres above the ground. Note that Steinernema feltiae does not control shore flies; however, the beneficial nematode Steinernema carpocapsae is available under the trade name Millenium to control shore fly larvae.

Also known as sciarid flies, these small black flies are quite irritating, but the adult flies actually cause little damage. In houses, ants are attracted to crumbs of food or food left out, particularly fruit and anything containing sugar. WHAT WILL HAPPEN TO THE EFFECTIVENESS OF THE BENEFICIAL NEMATODES IF THE WATER SOURCE AVAILABLE IS TOO COLD OR NIGHTS HAVE BEEN GETTING COLD, OR THE DAYS TOO HOT? Nematodes Steinernema feltiae are natural parasites of the fungus gnat larvae, which hide in your soil and hatch into new flies.

It took about 1 week after applying, and swatting every fly that remained flying around, for them to totally go.

Steinernema feltiae, an insect parasitic nematode, has been used extensively for fungus gnat control for many years. The bacteria kills the host within hours, and the nematodes grow and reproduce within the 'broth', which they produce. The beneficial nematodes will gradually sink to the bottom so stir occasionally as you pour to keep the nematodes distributed in the water. You can apply using a watering can with a course rose head or use a hose end applicator for larger areas.Growers interested in using biological control are encouraged to begin by using beneficial nematodes to manage fungus gnats. If using a watering can stir and pour a portion of the liquid into the watering can and add more water, then water pots or affected soil.
