- Target Pest Range: Some insecticides are multi-purpose while others specialize in silverfish. Choose based on whether you need wide pest control or focused treatment.
- Safety and Environmental Impact: Botanical or mineral-based insecticides can be safer around pets and children. Always check for usage restrictions.
- Size and Coverage: Choose product sizes that fit the area you need treated to avoid wastage or under-application.
- Ease of Use: Products with included applicators or pre-measured paks improve accuracy and reduce user error.
