Cyonara LP granules are very good, but so are the Bifen Granules
. The Cyonara granules will probably not yield any better results than the Bifen. A presence of springtails means there is usually a moisture issue under the house or around the house. Springtail eradication depends on eliminating the moisture source. If the springtails are breeding from under the slab, then the granules around the outside of the house will not effect them and they will be able to get into the house. It is imperative to correct any moisture issues or water that puddles up against the house. You could use Bifen IT
inside and on the house outside for some extra killing power in addition to the granules.
