How to Protect Old Family Photos from Pests

The short answer for how to protect old photos from pests is to store them in an airtight container rather than a cardboard box with a loose lid, add a silica gel packet to control moisture, and keep the storage spot dry, bright, and free of clutter, since pests like silverfish thrive in exactly the opposite conditions. Most people picture pest damage as something books or dry goods suffer, not photos, but silverfish and similar insects eat the same glue, paper fibers, and gelatin emulsion that make up a print. A box that looks untouched from the outside can hide photos that are quietly being eaten from the inside for years.

What pest damage to old photos actually looks like

Silverfish feed on the glue holding an album together and on the paper and emulsion of the photo itself, which is why damaged prints often turn up stuck to each other, curled at the edges, or thinned in patches rather than simply dirty. Look for tiny irregular holes, yellowish stains, or a fine dusty residue of shed scales on the surface or in the folds of an album page. The damage tends to start at the edges and in the gutter of a bound album, where paper layers sit close together in the dark, and can go unnoticed for a long time because nothing about a closed box or album looks disturbed from the outside. If prints have already stuck together, pest damage to the adhesive is one of the more common causes, alongside humidity.

Why pests go after photos in the first place

Silverfish and similar insects are drawn to starch, cellulose, and protein, all of which show up in a typical photo album: the paper stock, the glue in the binding, and the gelatin layer in older prints. They also prefer the same conditions many people unknowingly store photos in, a dark closet, an attic box, or a basement shelf that stays humid and rarely gets disturbed. That combination of food source and undisturbed darkness is what turns an ordinary storage spot into a pest habitat. It's a similar failure mode to the one that damages photos in a storage unit, where humidity and neglect do the harm even though the underlying threat is different.

How to protect old photos from pests

An airtight plastic container beats a standard cardboard box, since pests can't chew through sealed plastic the way they can work into a lid seam. Add a silica gel packet inside to keep humidity down, since a dry environment is far less hospitable than a damp one. Store the container somewhere dry and bright rather than a dark, undisturbed corner of a basement or attic, and check on it every few months rather than leaving it sealed away for years, since early detection is what keeps a small problem from spreading through an entire album. Regular light cleaning of the storage area also helps, since pests are drawn to dust and clutter as much as to the photos themselves. These same habits are the foundation of storing old family photos properly in general, pests are just one more reason to follow them.

What to do if photos are already damaged

A photo that's been chewed, stained, or stuck to its neighbor isn't necessarily gone. Scanning what's left captures the image before any more paper or emulsion is lost, and a skilled restoration can often rebuild missing detail digitally even when the original print can't be fully saved. Separate any stuck-together prints carefully before scanning rather than forcing them apart, since pulling too hard tends to tear the surface further. Once a damaged photo is safely scanned, it's also a good candidate for turning into a short video, since a moving version of the memory survives even if the original print keeps deteriorating.
