Ryan - We've had plenty of evidence of silverfish grazing in a few of our storage areas. Thankfully the damage was done to paper labels and tissue paper and not objects. We had a major cleaning of the space, in an effort to remove the silverfish food sources - cardboard boxes, the aforementioned paper items - and did a thorough vacuuming. We still have to go in again, however it is MUCH better then before. I'm anxious to try out the method you mentioned, Tom. Thanks again, Matt Matthew A.

For instance, makers of cellulose insulation treat the ground up paper with borates for fire retardancy. People assume silverfish eating the insulation or crawling on it will be killed. Definitely not true. One of the worst infestations I've witnessed was in an attic with cellulose insulation. Every artifact, box, all items, and the floor were covered with what looked like pepper. It was actually the droppings of millions of silverfish. Flat, cardboard glueboards often harbor silverfish UNDER them, where they eat the printing off the cardboard. Here's a trick for glueboard monitoring of silverfish. Use a small, flat cardboard glueboard. Place a penny in each corner of the glue and one in the center. Then turn the glueboard upside down and place it in areas where silverfish have been seen. Placement along walls and in corners of poured slab construction is especially effective because the silverfish hide in the gaps of the expansion joint material. The silverfish will seek the shelter of the glueboard and be caught.

In response, I used an electric power duster several years ago to broadcast Niban bait (very similar to Entice) throughout the attic void hoping to kill the silverfish in their native environment before they could get to the wall voids and spill out under cracks between the floor and baseboard. The results were minimal at best. Do you see evidence of silverfish activity in your storage spaces, or are you simply looking for a way to effectively prevent problems? Since we have notorious silverfish activity in the building referred to above, maybe I will try some Niban Fine bait on a few of our insect monitors to see what happens. I browsed the web this afternoon and am very curious about the effectiveness of the numerous pheromone traps that are listed for control of silverfish. Victor made a pheromone trap that was labeled for German cockroaches that worked miracles in some of the kitchens I serviced, both in early detection and population reduction.

Recently, upon the recommendation of our pest service entomologist and rep, we've placed a few sticky traps laced with "Entice", a boric acid based insecticide transported on a starch (I think corn based). Does anyone have any experience or opinion on either method of silverfish control? Which is better and proven so. Or maybe have another suggestions for baiting and killing/trapping silverfish? I would like to choose one proven method and implement it throughout. The DEKKO paks aren't cheap and tend to get kicked under shelving and objects, forgotten about until sucked up by a vacuum.
