Hi Elizabeth We've had great success with the Dekko silverfish baits, and you could supplement the baits with a perimeter spray of the area and treatment of voids (i.e. gaps around doors, skirting boards) with a suitable dust. The baits are relatively inexpensive, so throw them around the affected area like ninja stars (maybe place them instead). Freezing/removal of cardboard boxes where possible, and storing susceptible items in plastic boxes (silverfish can't climb slippery surfaces). I've also suggested that someone (cons students?) start investigating what starch is the most attractive to silverfish, so that we could make blunder traps more attractive, but in the absence of a suitable lure perhaps sticky traps along wall edges where the silverfish have been sighted to aid monitoring. Hope it all goes well over the next few months. Best wishes Alex
