Controlling silverfish in commercial settings: measures and long-term solution

Quick overview

Silverfish usually occur in commercial buildings in dry, warm areas such as storage rooms, archives, or office and hotel rooms and are often noticed late. Individual animals often already indicate an existing population. Control is not done with sprays but through monitoring to determine infestation and then targeted bait treatment along travel routes. Surface cleaning alone does not eliminate the infestation because the animals reside in cracks and cavities. In case of widespread occurrence or recurring sightings, systematic treatment is necessary.

Detect infestation

Silverfish are light-shy and are mostly discovered at night.

Signs Meaning
Single animals at night Beginning infestation
Multiple animals in different rooms Population present
Feeding marks on paper/cardboard Food source established
molting remains Permanent establishment
Sighting after cleaning Hiding place in structure

Immediate measures

After the first sighting, organizational steps should be taken:

  • Check cardboard and paper stocks

  • Keep storage areas dry

  • Move shelves away from walls

  • Identify cracks and joints

  • Do not use scented or contact sprays

  • Set monitoring points

Suitable control method

Silverfish live permanently in buildings and reproduce slowly but steadily. Since they mainly reside in cracks, under floors, or behind moldings, direct control is hardly possible. Effective control is a combination of infestation detection through monitoring traps and subsequent placement of bait systems along travel routes.

Unsuitable methods

The following measures rarely lead to success:

  • Contact sprays

  • Home remedies like lavender or citrus oil

  • One-time vacuuming

  • Individual traps without a system

These methods repel animals temporarily but do not change the population.

Decision aid

Situation Measure
Single animals at night Start monitoring
Regular sightings Supplement bait system
Multiple rooms affected Area-wide treatment
Animals still visible after weeks Follow-up treatment
Increasing numbers Check for structural problems

When systematic treatment is necessary

Further measures are required when:

  • Sightings on multiple floors

  • Infestation in guest or office rooms

  • Damage to materials

  • recurring sightings after cleaning

  • permanently warm-dry rooms

Prevention in commercial settings

Long-term control significantly reduces reinfestation:

  • Do not store cardboard permanently

  • Control humidity

  • Seal baseboards

  • Conduct regular monitoring

  • Rotate stock

  • Check cavities

Suitable product types

Bait stations
reduce population by uptake of the active ingredient

Monitoring traps
used for infestation monitoring and location determination

Sprays
not suitable for sustainable control
