Product
How long does it take to work?
Most customers notice less bug activity within 24–72 hours. Treated areas quickly become less inviting.
Is it safe around kids & pets?
Signal Strip is made with plant-based ingredients — peppermint, lemongrass, clove, cinnamon and geraniol — with no toxic chemicals or sprays. As with any household product, place strips out of reach of children and pets and don’t let them chew or swallow the strips.
How is this different from sprays?
Sprays fade fast and leave residue. Signal Strip works continuously with a slow-release, plant-based formula — nothing to spray, wipe or clean up.
Will it keep bugs away or just move them?
The scent barrier makes treated areas somewhere bugs avoid, so they stop using those entry points instead of settling in.
Does it smell strong?
You may notice a light, fresh mint and citrus scent close to the strip. It’s designed to be noticeable to bugs, not overpowering for you.
Using Signal Strip
How many strips do I need?
Use 1 strip per key entry point. As a guide: small area 2–4 strips, main living area 4–6, average home 8–12, large home 12–16. Every pack contains 12 strips.
Where should I place them?
Along entry lines: door edges, windows, baseboards, under sinks, behind appliances, pantry corners, pipe entries and garage access points. See the full placement guide.
How long does one strip last?
Each strip stays active for 30–45 days. Replace it after that for continuous protection.
Do I need to do anything besides placing it?
No. Just place it — no setup, no maintenance. Replace every 30–45 days.
