HARRIS Roach Killer liquid spray — 1 Gallon odorless, non-staining formula with 12‑month residual

HARRIS Roach Killer is a one‑gallon, odorless liquid spray that delivers an extended residual kill—remaining effective for up to 12 months after application when used as directed.

This concentrated gallon of HARRIS Roach Killer comes with an extended trigger sprayer to treat hiding places and high‑risk zones across homes, apartments, and commercial spaces. The non‑staining, low‑odor formula is EPA‑registered for indoor use when label directions are followed, offering a cost‑effective option for recurring or large‑area treatments without irritating smells or fabric damage.

How does this spray keep working after application?

Once the liquid fully dries, active residues remain on treated surfaces and continue to affect roaches that crawl across them. The extended residual action helps interrupt reinfestation for weeks to months depending on conditions and surface type.

• Residual activity lasts up to 12 months under label conditions.
• Effective when applied to baseboards, cracks, crevices, and voids.
• Continues killing pests that contact treated surfaces after drying.

Is it safe to use around family and pets?

HARRIS Roach Killer is EPA‑registered for use in homes, which means it meets regulatory standards when applied per instructions. As with any pesticide, keep people and pets away from wet spray and follow reentry and drying guidelines on the label to minimize exposure.

• EPA registration number included on the product label.
• Avoid direct contact with wet spray; allow surfaces to dry thoroughly.
• Follow label instructions for areas accessible to children and pets.

Will it stain fabrics or leave strong chemical odors?

The formulation is designed to be non‑staining and low‑odor so it can be used near textiles and living areas without obvious residue or lingering smells. Proper application—spraying only recommended surfaces and avoiding oversaturation—reduces the chance of stains or noticeable scent.

• Odorless formula minimizes nuisance smells after application.
• Non‑staining when used according to label directions.
• Ideal for kitchens, basements, garages, and utility rooms.

How much area does one gallon cover and how is it applied?

A single gallon gives substantial coverage for repeated treatments in medium to large spaces, making it economical for whole‑home or multi‑unit use. The product ships with an extended trigger sprayer to reach cracks, crevices, and hidden harborage where roaches hide.

• One gallon allows for multiple applications across rooms or units.
• Extended trigger sprayer helps reach tight voids and edges.
• Apply to baseboards, behind appliances, and in cupboards per label.
