Scanmask Beneficial Nematodes, 25 Million Active Units

Nontoxic! They work.

These killed all my fungus gnats and I am now gnat free...finally! Very easy to apply, took about a week or two for the effects to be visible. It gets the job done!

Several reviewers complained about lack of information. If you click on the image, it also shows 4 pages that you can choose to enlarge and those have all the information about species and application options.

I agree with the former two reviews appearing here. In all fairness, the ad format does not allow room for exhaustive technical information. With that in mind, it would have been wise of the seller to at least include a means of technical assistance for pre-purchase contact.... I could not find anything on the page that would allow me to make an informed decision about purchasing this item. Information revealing species type, application rate, and expected coverage area would have been helpful, not to mention a guarantee for live delivery... The "number of units left" information is NOT sufficient evidence for me to justify a $50.00 expenditure.

Without knowing the species it is hard to justify purchasing.

There are a plethora of nematode varieties out there, many tailored for specific applications.It would be nice if the seller would provide sufficient information to make an informed purchase--possibly starting by identifying, with specificity, the species of nematode being offered for sale. Application data, from the USDA, would also be of assistance to many purchasers.As it stands, currently, this listing is worthless.

I can't use a product that does not give me technical data such as application rate and the benefits of the particular nematode being offered in this product. What insects do these nematodes treat?

seem to do the job they stated.
