Description

Steinernema feltiae are beneficial nematodes used to control fungus gnats and western flower thrips in the soil. Nematodes are safe for plants, people and pets and are an organic solution in place of harmful pesticides. S. feltiae are active in cooler weather and will survive and infect hosts in temperatures as low as 50°F.

Life Cycle

A complete life cycle takes 12 to 15 days at room temperature. Media temperatures should be above 50°F but not more than 88°F. Optimum media temperatures are between 60-70F. The nematodes enter the insect pest through body openings. Once inside they reproduce and release a symbiotic bacterium which is toxic to the host. The pests are killed within a few days and a second generation of infective juvenile nematodes exit the host and begin the cycle again. Use beneficial nematodes as part of an IPM program.

Entomopathogenic nematodes are supplied as infective juveniles, which are usually applied as a soil drench. Not all nematodes are alike. They specialize in which pests they attack and kill and are effective at different temperatures. 

Application Rates

Beneficial nematodes come in two forms. Sponges that are pre-inoculated with infective juveniles in quantities of 1 million, 6 million and 24 million. Generally, in a greenhouse setting, apply these beneficial nematodes at a rate of 1 million per 1,000 sq. ft. The sponge product has a completely unique application rate as the bacterial level is much higher because they are produced in vivo. 

Sponges - Nematodes from Sierra Biological are packed on a sponge of pure cellulose wood fiber that is hydrated with water for shipping. The sponges do not go into the crop, only the nematodes, once they have been mixed with water. 

Trays - contain 50 million or 250 million. Release every 2-3 weeks at a rate of 50 million/1100 sq. ft. or every 4-6 weeks at a rate of 50 million/550 sq. ft.  Use 30-50 gallons of water/1000 sq. ft. for applications onto soil or growing media. Some of these are certified organic. 

Instructions for Use

Apply nematodes with a sprayer, injector, hose end sprayer or even a watering can. Plug trays can be dipped in a nematode solution. If using an injector, set the dilution to 1:100. It is important to remove all filters or screens (50 mesh or finer) in any spray lines so that the nematodes can pass through unimpeded and undamaged.

Keep spray pressure below 300 psi. For every square foot you will need .66 gallons of water as the carrier. Saturate soil or potting media to a depth of 2". See Nematode Tech Sheet for further information. Broad spectrum pest control without toxic chemicals. Shipped fresh and quality guaranteed.

Fresh, Clean Air — Excellent Quality Cabin Filter!
Size: 9.7" x 9.3" x 1.8"
This premium HEPA‑rated filter does an outstanding job of keeping dust, pollen, and tiny airborne particles out of the cabin — much better than standard cabin filters. It’s designed and tested to meet true HEPA filtration standards, effectively capturing up to 99.97 % of particles down to 0.3 microns in size, so the air inside the car feels noticeably cleaner and fresher. Installation was straightforward and fit exactly in place in my vehicle with no modifications needed. The high‑quality filter media feels dense and well‑constructed, with built‑in structural support to help it hold its shape throughout its service life.

Must Buy HEPA Cabin Filter
Size: 9.7" x 9.3" x 1.8"
Great filter and excellent Value! And, it’s a Bosch !!! Description and sizing were exactly as advertised. DIY install was easy and it fit my 2019 Highlander perfectly ! Filter is HEPA and well made and is a good thickness, so much better than the flimsy one the car dealership installed. Impressive ! Highly recommend!

A Lungful of Freedom
Size: 9.7" x 9.3" x 1.8"
Dateline: The Passenger-Side Footwell of a Toyota Venza, Sunday Night. We spend our lives in sealed metal boxes, hurtling through a thick, invisible soup of our own collective filth. A foul cocktail of exhaust fumes, road dust, tire particles, and whatever strange, pollen-based miasma the world decides to throw at us on any given day. To breathe that poison in, unfiltered, is an act of slow, unwitting suicide. You need a line of defense. A gatekeeper for your own lungs. Enter the Bosch 6055C HEPA Cabin Air Filter. It is not a glamorous part. It is not a performance upgrade that adds horsepower or prestige. It is a simple, pleated rectangle of paper and charcoal, a humble guardian destined to live out its days in a dark plastic cave behind your glovebox. But its mission is a noble one. The replacement process is a moment of pure, unadulterated, five-minute victory over the dealership's service department. You pop open the glovebox, you unclip the old filter tray, and you pull out the old soldier. And what you find is a horror show. A grey, matted testament to the unseen war it has been fighting on your behalf, choked with leaves, dirt, and the ghosts of a thousand diesel trucks. It is the face of the enemy. You unwrap the new Bosch filter. It feels solid, well-made. The pleats are clean and numerous. I laid it side-by-side with the outgoing Denso filter—a brand that supplies the automakers themselves—and I could find no meaningful difference. The quality was equal. The construction, robust. This was no flimsy, cut-rate pretender. This was a serious piece of hardware from a serious company. You slide the clean, white Bosch into the tray, snap it back into its dark little home, and close the glovebox. The deed is done. You have performed a life-saving transplant on your vehicle's respiratory system in less time than it takes to listen to a single pop song. And the value… the value is the sweet, sweet punchline. For a fraction of what a dealership would charge you for the same simple service, you have installed a top-tier, HEPA-grade filter from one of the most respected names in the business. You have guaranteed yourself a clean, breathable bubble of personal space as you navigate the toxic jungle of the modern roadway. This is not just a filter; it's a small, affordable act of rebellion. It’s a declaration that you, and you alone, are the master of the air you breathe. It is a simple, effective, and profoundly satisfying piece of gear. Highly recommended.

Great Upgrade to your Cabin Filter. Fits 2018 Subaru Outback
Size: 9.7" x 9.3" x 1.8"
This is a great filter upgrade to your cabin filter. This is better than the Subi standard part. Fits my Subaru outback. NOTE: Subi marks their filter with an 'up' arrow; however, this filter is marked with a 'airflow' direction. Direction of air flow is toward the blower motor so it will point downward when you install it.
