How to Get Rid of Silverfish
Step 1) Perimeter Treatements with Pesticides
The most effective chemical control method for silverfish extermination is to apply a perimeter treatment both inside and outside the infested structure.
First, apply a residual pesticide labeled for silverfish ( Demon WP Insecticide or Suspend SC both provide excellent results) with a Gallon Sprayer around the entire outdoor perimeter and indoor along baseboards.
Next, using a Hand Duster, apply waterproof residual Delta Dust Insecticide (lasts up to 8 months) underneath baseboards, inside of cracks and crevices, and behind cabinets.
CB Intruder HPX may also be used and kept on hand for contact kill when silverfish are sighted on countertops or walls. This aerosol product may also be used around window and door frames (providing a 4 to 8 week residual).
You should also try Dekko Silverfish Paks. Dekko packs are an economic and easy way to control silverfish. Silverfish simply eat through the pack and ingest the poision inside. Place two to three packs in each infested area you are trying to control. Silverfish may take several days to a few weeks to control using this method, depending on the severity of the infestation.
Step 2) Nonchemical Control Methods
In Silverfish pest control, it is important to use both chemical and non-chemical methods for total control. Pesticide application will go a long way towards getting rid of silverfish, however total population control can only be achieved by also eliminating existing conditions that support the infestation.
Nonchemical methods for silverfish pest control are:
Physical Removal- For heavier infestations, large numbers of silverfish may be removed using a vacuum. After removal, the vacuum bag should be sealed in a plastic bag and discarded.
Harborage Removal- Harborage removal is key to lasting silverfish control. This includes eliminating piles of lumber, bricks, and other stacked items that create clusters of tight spaces, elimination of grass and leaf litter near homes and buildings, trimming back tree and shrub limbs from walls and roof, and keeping gutters clear of leaves and other debris.
Managment of Excess Moisture- Silverfish thrive on excess moisture. Foundation moisture can by minimized by adjusting the direction of irrigation sprinklers, and watering in the morning rather than the evening so that the sun can dry vegetation quickly. Attics and crawlspaces should be properly ventilated.
Exclusion- Silverfish and other pests can be kept out of structures to a large degree by installing tight-fitting screens, weather-stripping around doors and windows, and caulking cracks and crevices.
Traps- Sticky traps placed in or near infested areas may reduce silverfish populations
