Silverfish Infestations On The Rise Due To Wet, Warm Summer Conditions

An additional problem that has come about from the continued wet summer combined with reasonably warm temperatures is the prevalence of silverfish in the home or business premises.

They are a flat, elongated insect usually 13-25 mm in length. Older members of the silverfish population have a shiny, metallic shine to them, with young being born almost white in colour, developing a greyish colour as they grow.

Silverfish have two small eyes and three long cerci. They tend to hide throughout the day and become more active at night.

They seem to be flourishing in buildings which have a cold concrete floor, with moisture underneath as a result of wet weather. They also can be found in garden and perimeter walls where moisture makes these ideal harbourages.

We have recently been called out to a children’s nursery in the West Midlands which was suffering with an infestation of silverfish.

Their eggs can be recognised (often in crevices) by their oval, white appearance around 0.8 mm in length.

As well as providing pest control to remove a silverfish problem, we are able to advise on some of the ways of ensuring the problem does not occur by removing the ideal environment for them.
You can remove old boxes, papers, magazines etc. as they often feed on paper products, books, fabrics and even wallpaper. They can also consume most human food so clearing away scraps is always a good idea.

Roof leaks can also be repaired to help to remove some moisture. Moisture in sub-flooring and exterior walls can also help create ideal conditions. Plumbing leaks and condensation on air con systems etc. can also add to the issue.

Once we have advised on the removal of materials which may be exacerbating the problem we can carry out treatments including insecticide or use of light to solve the problem. We can also carry out an inspection to assess how likely the problem is to have spread over longer distances around the building and advise and act accordingly. Controlling a widespread problem may not be solved overnight and issues with moisture should be tackled as part of a treatment and prevention program to resolve silverfish problems and infestations.
