SILVERFISH EVERYWHERE!!!!!!!!!!

Anyone that has experience with this, please help! I've done extensive research on these silverfish and it's all mainly generalized info. I kill at least 1 every night on the ceiling in living room. I've seen 2 at same time in attic. Killing 1 a day since last January! How can I get rid of them?!?!? I know they like moisture and cardboard and we have a storage room in basement with boxes yet I've NEVER spotted one down there. These pricks are just on the main level and what I've seen in attic. There's no real moisture issues other than typical house repair crap but they're everywhere. Where do they nest? What repels them? I do spray orkin stuff outside around house every few weeks when it's nice out but I see them year round!! Anyone got any good intel on these silverjerks? Thx

 

Use diatomaceous earth. Lets the pests slowly disintegrate when they come in contact with them.

 

Where do i spread the stuff and is it just a basic diatomaceous earth?
