Product Information

Larvae: Vine weevil grubs can be controlled by watering into compost or soil a suspension of pathogenic nematodes.For best results nematodes need to be used in a well-drained potting compost or light soil, which must be moist. Treatment in August to early September should control vine weevil grubs before they are large enough to cause serious damage to plant roots. Fungus gnats are attracted to moist soil and planting media, which is why overwatering houseplants is perhaps the most common cause of fungus gnat infestations. Q. Should I dispose of infested soil in my potted plants to get rid of fungus gnats?

Practice good plant hygiene by removing any old, dead leaves and fungal growth from the top of pots. You will also need to continually remove organic debris from the soil, as this is the kind of material that the fungus gnats like to feed on. On a regular basis, rake up dead leaves, grass clippings, flowers, and other debris from your yard and potted plants. After you’ve cleared any organic waste from the soil, add some diatomaceous earth to the potting soil. The symbiotic bacteria carried by the nematodes break down the host insect's cuticle. The infected larvae rapidly disappear, so they may be difficult to locate. Infected fungus gnat larvae are often opaque and white to light yellow in color.

Most nematode species feed on microbes, while some prefer to eat living matter, such as larvae and grubs, that can damage your lawn. This is what makes them popular in the war against lawn pests. Use these critters in your garden The first symptom of damage that you’ll notice is wilting and a general decline in the health of the plant. Read on to find out how to kill fungus gnats with simple DIY remedies. How to Control Fungus Gnats If you don’t have pets and are looking for how to kill fungus gnats safely, consider spraying your plants and the surface of their soil with a pyrethrin solution. Pyrethrins are natural insecticides that don’t harm humans, but reportedly can be harmful to pets—cats and fish in particular.

When vine weevil larvae are present, and soil temperatures are above 12°C for at least a few hours per day (April to October).Fungus gnats are tiny flying bugs belonging to a few insect families (namely Sciaridae, aka dark-winged fungus gnats). They eat plant matter, mulch, compost, and—true to their name—fungus. All of these materials can be found outdoors, but these dietary needs can be found even more reliably in potting soil for houseplants. Their attraction to potting mix’s warmth and moisture makes fungus gnats particularly problematic indoor pests. You can top dress your houseplants with Steinernema feltiae, or beneficial nematodes to destroy the fungus gnats during their larvae stage. The microscopic roundworms penetrate the fungus gnat larvae, then release a bacterium that works to consume the insect from the inside out. They are safe to use around plants, pets, and your family. The presence of biological controls should not interfere with normal gardening activities such as ventilating glasshouses and watering, although it is necessary to avoid the use ofpesticides The microscopic worms travel through the soil, hunt down the larvae version of the pest, and kill them.

Place the hydrogen peroxide and water into the spray bottle. Replace the lid and gently shake the bottle to combine the ingredients. Allow the top of the potting soil to dry before you begin the treatment. Spray the solution under your plants, over the top of the soil. Solarize potting soil and compost to sterilize it. To do so, place soil inside of a sealed plastic bag and pat it flat so that it is no more than 8 inches deep. Lay it on a raised location in the sun for at least a month—or two months or longer in cloudy places. Marigolds make great bedding partners for carrots, celery, and onions to help keep invading species at bay. Alternatively, plant marigolds in your fallow soil — that will also keep the nematodes away. Any questions Along with being useful in adding flavor to meals, cinnamon is also a natural fungicide. To get rid of gnats in plants and kill the fungus gnat larvae, you can sprinkle some cinnamon on the surface of the potting soil of your houseplant or garden beds. The cinnamon will kill the soil gnats. Use Hydrogen Peroxide to Kill Fungus Gnats Control:NematodesVariousproductscontaining Steinernemafeltiaeand S.carpocapsae,including Nemasys Fruit and Veg protection andBox tree caterpillar killer.In the third bioassay with P. ostreatus, significantly fewer fungus gnats emerged from the Bti compared to the S. feltiae treatment and the untreated control ( Figure 4C). Significantly fewer fungus gnats also emerged from straw treated with S. feltiae compared to the untreated control ( Figure 4C: F 2, 27 = 24.53; p< 0.0001). The Bti treatment resulted in an 88% reduction and S. feltiae treatment resulted in an 53% reduction in fungus gnat emergence compared to the water control. Several species and combinations of species can be available including, Steinernema kraussei, S. feltiae, Heterorhabditis megidis and H. bacteriophora. Steinernema species can remain active at soil temperatures down to 5ºC (41ºF) whilst Heterorhabditis require temperatures above 12ºC (54ºF).

Fungus gnats can affect everything from succulents to tomato plants. They can also infect potting soil bags, which is a very common route of entry into your plants. Media temperatures should be above 50° F but avoid applying when soil temperatures are above 80°F. Optimum media temperatures are between 60-70°F. Use a soil thermometer to monitor temperature. Fully-grown plants are much less likely to be damaged, but can be if there's no other food source for the Scaridae. Where do gnats live? They can be found hovering around your plant, or crawling over them. Indoors, you will notice a gnat slowly flying around the room. They’re attracted to light, as well as heat and scent. For this reason they may seem attracted to you as well.Parasitoid wasps Metaphycus helvolus, Encyrtusspecies and Encarsia citrinaare sometimes available. These parasitoids lay eggs inscale nymphs, which become darkened and are killed. At 27ºC (80ºF) the life cycle from egg to adult wasp takes about 12 days but is slower at lower temperatures. These parasitoids should be introduced in May to July for the best results. Various methods of controlling or eliminating fungus gnats with biological pest control have been developed. For example, Bacillus thuringiensis israelensis (BTI) is known to produce proteins that can kill fungus gnats larvae and some other insects like mosquitos. [17] [18] [19] [14] BTI is a naturally occurring bacteria that has been used for decades—the United States EPA reports that it has no toxicity to humans. [17] Several dozen products containing BTI have been approved for residential, commercial, and agricultural use in the United States. [17] The israelensis subspecies is suggested because other types of Bacillus thuriniensis (BT), such as those for controlling caterpillars, are ineffective at controlling fungus gnats. [14] Repot houseplants with new potting soil frequently. Although fungus gnats live outdoors, too, they generally don’t cause problems in open spaces. Repotting indoor plants gives fungus gnats fewer opportunities to overtake containers. For the best way to learn how to get rid of a gnat infestation,you should know that there are many ways to get rid of gnats that don’t require you to spend a ton of money.
