The nematodes are then reared in state of the art liquid fermentation facilities before being formulated into a product which is able to keep the nematode in an alive but dormant state so that it reaches the grower in the best condition. So, it’s essential to choose the right nematodes for your garden. Typically, the nematodes available online and in garden centres are safe for domestic use. The nematodes kill the vine weevil larvae, which do the most damage to the plant by eating the roots. This also prevents new adult vine weevils from hatching.

The whole lifecycle is about 28 days, but the adult fungus gnats live only around 7 days. Where do fungus gnats come from? Environmentally-friendly: only kills the targeted pest, safe for birds, bees, and other beneficial wildlife

Biological Control

Fungus gnats are attracted to moist soil and dark, humid environments, so they're a common houseplant pest. They're not actually attracted to the plant but the soil, so they can be found on all kinds of plants. 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.

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 Cabrera AR, Cloyd RA, Zaborski ER. Effect of monitoring technique in determining the presence of fungus gnat, Bradysia spp. (Diptera: Sciaridae), larvae in growing medium. Journal of Agriculture and Urban Entomology. 2003 Jan;20(1):41–47. For more detailed information on pesticide compatibility, consult with your supplier or with the following resources on the Internet: Young bedding plants, especially bizzie-lizzies, can be affected with large numbers of small flies covering young plants, whilst larvae eat the roots. Clean up all freestanding water on solid benches, on walks, and under benches. Be sure that cooling pad distribution tubes are not leaking. Avoid overwatering plants.This approach is most successful during a long hot summer when the soil is likely to dry out. Keep the fallow soil weed free, or the nematodes will eat those instead. Marigolds and Tagetes — nature’s natural remedy

The chive gnat, Bradysia odoriphaga Yang and Zhang, feeds on more than 30 species plants of at least seven families ( Zhang et al., 2016). On Chinese chive ( Allium tuberosum Rottler ex Sprengel), an important perennial herbaceous cash vegetable in eastern Asia, B. odoriphaga causes 30 to 80% yield losses, and in severe cases, the crop must be replanted ( Ma, Chen, Moens, Han, and De Clercq, 2013). The larval stages of B. odoriphaga are cryptic in the soil, and therefore excessively toxic pesticides have been used by farmers leading to pesticide contamination ( Yang et al., 2010; Watanabe and Miyake, 2018). Pesticide applications are required after harvest, before a production cycle. The risk of human poisoning is considerable due to the relatively short period between harvest and pesticide application (15-20 d). In addition, overuse of pesticides has also led to the development of pesticide resistance in B.odoriphaga, even for neonicotinoids ( Chen et al., 2017, 2019). Our study, based on results of the plate and pot experiments, shows that EPN application and waterlogging both had negative effects on B.odoriphaga populations. Longer waterlogging times led to higher death of B. odoriphaga, and all EPN species caused mortality in B. odoriphaga larvae. Most importantly, waterlogging and EPN addition interacted positively on B. odoriphaga mortality. The combined treatments of EPNs and waterlogging caused higher mortality in B.odoriphaga larvae than either of the treatments alone. Water from the bottom using a tray, rather than the top. Since the eggs tend to be laid near the top of the soil, this prevents the top section becoming too moist. Figure 1. Fungus gnat larvae.

The nematodes can travel through the moist soil and locate the fungus gnat larvae. They then burrow inside and reproduce, killing the larvae and creating more nematodes to hunt down more larvae until none are left. Once the larvae are gone, the nematodes have no prey and naturally die out. Braun SE, Sanderson JP, Wraight SP.
