How to get rid of silverfish
Silverfish are fairly tricky pests to get rid of as they move very fast and usually only active at night. To get rid of a silverfish infestation you need to target the right areas with effective silverfish killer products.
If you already have Silverfish in your home then using a silverfish killer spray directly at them will be a quick way to kill any visible ones. Since Silverfish are normally hard to see the best way to get rid of them is to use a diatomaceous powder. This powder is very effective and is best when shaked into cracks and crevices where silverfish may be harbouring and along areas where they may be active e.g. around skirting boards, pipes etc.
If you are wanting to target an entire area quickly then we recommend using a silverfish smoke bomb. This can be a cost effective and time saving solution as the insecticide fumes will penetrate all areas of the room, especially those hard to reach areas where they may be hiding.
