What bug has a small gray body and three antennas?

Question: Recently, I have had a small problem with a weird-looking insect that I have never seen before. It’s real small and seems to congregate under wood such as plywood.

It has a slender gray body that is broader at the head and tapers down towards the end; it also has three antennas.

Would you be able to tell me what this bug is? I thought it was some sort of termite, but all the images of termites I have seen do not resemble this thing. Your assistance is highly appreciated.

ANSWER  From your description, I think it may be silverfish or a closely related species. With a specimen the identification would be conclusive.

The silverfish (Lepisma saccharina) is often found around the home. They have probably found a food source under the plywood. Silverfish also like moist areas. Their preferred diet is sugars and starches, so they can damage books and documents.
