What’s the best way to get rid of ants inside the home

If the product you used mostly worked, you may want to try a second application to wipe out the rest of the colony.

After doing some research there doesn't seem to be any tried and true solution to killing the ants (at least none I could find, I'm sure there are tricks exterminators use that they don't want to share), but most solutions seem to involve drowning the ants (in hot possibly soapy water).

You may want to contact your local pest control specialist, as I'm sure they have dealt with this problem before and no doubt have their own methods. Also having somebody else mess with the ants keeps you safely away from angry fire ants.

The least desirable solution I read about was to dig up the mounds, and "fling" the ants as far as you can. They did mention to make sure you fling the ants down-wind, but I wonder how many times they got a face full of ants before they came up with that little tip :).

Silverfish like cool, damp locations and feed on paper and other starchy materials. If the source of your silverfish problem is a crawlspace you might improve things by laying down heavy plastic sheeting over the ground and making sure it's properly vented to reduce moisture a little. Otherwise, silverfish are very annoying but basically harmless (except to your valuable books/documents- keep them sealed up).
