Buying Guide: Key Purchase Considerations
-
<li Indoor vs. perimeter focus: Choose barriers for long-lasting indoor protection or fast-acting foggers for quick knockdown as needed.
<li Target pests: If bed bugs or fleas are a concern, select products specifically labeled for those pests; for general household control, broad-spectrum options work well.
<li Surface compatibility: Barrier sprays are often designed for nonporous surfaces; consider porosity of floors and walls when applying.
<li Application method: Comfort Wand or spray applicators provide precision; foggers require careful room preparation and ventilation.
<li Safety and pets: Review product labels for pet safety, lingering odors, and necessary re-entry times after treatment.
<li Odor and residue: Botanical or low-odor formulas can be preferable in bedrooms or living spaces; consider potential residues on fabrics.
<li Long-term protection: Some products offer up to 12 months of protection on nonporous surfaces, while others provide shorter windows—plan accordingly for seasonal pest patterns.
<li Integrated approach: For persistent problems, combine indoor barrier sprays with traps, sanitation, and exclusion methods (sealing entry points, sealing cracks, sealing around pipes).
<li Environmental impact: Plant-based or low-VOC options may reduce chemical exposure while maintaining efficacy.
