The beauty of hunting silverfish is that they are not the most clever of creatures in the insect kingdom.
Simply take a small clean glass jar and wrap it in masking tape. The masking tape gives the silverfish something to cling on to as they curiously climb to the top of the jar. Bait is not required. Set the jars upright in the path of known offenders, sit back and wait…OK, perhaps just leaving the jar and coming back in a day or two will do.
