get rid of silverfish

I want to get rid of silverfish and have two questions.
1) I was considering spreading Niban FG in a wide-open, unobstructed attic for silverfish control (I don’t know how many or where they are nesting, but thought that a this treatment, together with the treatment below may take care of it).  Based on the photo, it seems like the particles are large enough that they might be spread using a Scotts hand held broadcast spreader (sold in lawn and garden centers).  Would this work or would a Dustin Mizer do a much better job (throw the particles further or more uniformly).
2) I was considering also applying an insecticide in liquid form (using a pressure sprayer) over the entire floor area of the attic (unfaced fiberglass), just slightly wetting the surface.  Can you recommend an insecticide for this purpose?
Thanks in advance.

As explained in our SILVERFISH CONTROL ARTICLE, it’s best to use bait in wide open areas where silverfish are being seen. Since you’re unsure where they’re coming from, it’s definitely easier trying to lure them to a bait compared to trying to get every entry point covered with a spray.The NIBAN is excellent for this use and may be the right choice for the wide open area you mention above in section 1).

That being said, if you don’t have too many areas that lead into that room, you could opt to treat with some PT-PHANTOM. This is a new compound, slow acting and odorless, which has the unique feature of appearing “dry” when applied. This makes it well suited to use inside compared to wet or liquid sprays like you’d get when using our ESFENVALERAT’E CONCENTRATE. So for the second part of your question, in 2), I’d say to use the Phantom which will effectively eliminate any “wetness” issue where sprayed and do a great job in the long run. I use it on my boat for spider control and it’s ideal for the shiny surface of the deck. You don’t even know it’s been applied and within minutes of the application it’s dry and pretty much invisible. This feature will enable you to treat the area thoroughly and avoid overspray.

Lastly, it will really help if you’re somehow able to identify where these guys are originating. Getting them in their “nest sites” is always the best approach and in the long run will make total control an achievable goal.
