Sciarid fly also known as fungus gnat or compost fly is a frequent pest in houseplants, greenhouses and conservatories. Sciarid fly nematodes Steinernema feltiae provide a natural method for reducing this pest in soil based growing areas.

How Sciarid Fly Larvae Affect Soil and Why Nematodes Help

The larvae of the sciarid fly feed on plant roots and young seedlings which can lead to poor growth or plant loss. When introduced to moist soil these nematodes locate the larvae and begin reducing the number of sciarid flies present.

How Sciarid Fly Nematodes Work in Soil to Target Fungus Gnat Larvae

Sciarid fly nematodes are microscopic soil dwelling organisms that naturally target fungus gnat larvae. Mix the nematodes with water and apply the solution to areas where fungus gnats are active. Once in the soil the nematodes move through the moisture seeking out larvae.

What Happens When Nematodes Enter Sciarid Fly Larvae

When a nematode finds a larva it enters through tiny openings such as the mouth or breathing points. Inside it releases bacteria that cause the larva to die within one to two days. The nematodes then feed on the bacteria and the dead larva allowing them to develop and multiply.

The Ongoing Cycle of Nematode Activity in Moist Soil

After reproducing new nematodes leave the dead larva and continue to search for more larvae. This cycle repeats while the soil stays moist and larvae remain present.

Supporting Sciarid Fly Control with Yellow Sticky Traps

It is good for small yards but not so good for distance.
Size: 1-pack
Getting used to a ball thrower takes practice. This one is no exception. The angle is off for me. If I use it as an extension of my arm it goes straight to the ground, but once I got the hang of it. Balls launch with great height. Distance isn't a feature for this tool.

Get a longer launcher. This only throws 30 ft
Size: 1+3pack
Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.

These are dog tested and approved.
Size: 1-pack
The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.

This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend
