Buying Guide

Match active ingredient to pest type

Choose formulations aimed at your target: citronella/lemon-eucalyptus or peppermint oil for mosquitoes and general repellency, pyrethroid-based sprays for indoor crawling insects and perimeter control

Consider application area and format

Select outdoor personal sprays for skin-safe repellency or larger concentrate/perimeter sprays for yards and indoor perimeter treatments to control ants, roaches, and other pests

Check safety for people and pets

Opt for plant-based, DEET-free, or explicitly pet-friendly labels if you need lower-toxicity options around children and animals; follow label directions for safe use

Look at coverage and duration

Compare product sizes and stated protection periods—longer-lasting, larger-volume sprays often provide better value for treating yards or repeated indoor perimeter applications

Watch for odor and staining

If indoor use or near fabrics is planned, prefer odorless or non-staining formulas to avoid lingering smells and fabric marks
