Silverfish treatment tends to sit at the more affordable end of household pest control, but the price you pay for the pest treatment itself is often only part of the real cost — since silverfish are usually a symptom of an underlying damp issue that needs addressing too.
Typical Price Ranges
Professional silverfish treatment across London generally falls in the £80-£150 range for a domestic property, usually covering one to two rooms in a single visit. Silverfish are often grouped with other “low-risk” household pests by local providers, which tends to keep the price lower than treatments for pests requiring multiple follow-up visits, such as bed bugs or moths.
A silverfish problem limited to one bathroom is a smaller job than an infestation spread across a bathroom, kitchen, and airing cupboard, and pricing usually scales with the number of rooms treated.
This is the factor that matters most for value, even though it isn’t always reflected directly in the treatment price. A silverfish treatment carried out without fixing the leak, poor ventilation, or condensation attracting them in the first place is likely to need repeating, since the conditions that drew them there in the first place haven’t changed.
Number of Visits
Many providers treat silverfish in a single visit — Oldham Council’s pest control service, for instance, notes that its silverfish treatment involves just one visit — since, unlike pests such as bed bugs with resilient eggs, a thorough application usually clears an existing population effectively. Some providers include a follow-up as standard if activity continues; others charge separately.
Because silverfish thrive specifically in moist conditions, a treatment that kills the current population without resolving the moisture source is treating the symptom rather than the cause. If silverfish keep reappearing after treatment in the same bathroom or cupboard, that’s usually a signal to get the underlying dampness looked at — a plumber for a leak, or simply better ventilation — rather than repeating the pest treatment on its own.
The Extermination process includes a thorough inspection of your property, sealing off entry points to stop future infestations, using safe and effective pesticides and rodenticides, and providing a warranty.
Often, yes. Silverfish don't have the resilient egg stages that make pests like bed bugs or moths require multiple follow-ups, so a single thorough treatment is frequently enough to clear an existing population.
This is almost always a sign that the underlying moisture source — a leak, poor ventilation, or condensation — hasn't been addressed. Treating the insects without fixing the damp tends to result in the infestation returning.
For a handful of sightings in one bathroom, improving ventilation and reducing humidity may be enough on its own. A professional treatment becomes more worthwhile if you're seeing them regularly or across multiple rooms.
Many London councils offer silverfish treatment, often at a lower price bracket alongside other low-risk pests like beetles and woodlice, though pricing and inclusions vary by borough.
Either order can work, but addressing the moisture source is essential either way. Fixing it beforehand can sometimes reduce activity enough that treatment is more effective; fixing it afterwards still matters to prevent the infestation returning.
