How To Choose The Right Roach Killer?

  • Type: Based on the amount of roach infestation, choose from these three types of roach killers.
  • Surface sprays: They provide long-term control and can be applied on crevices, dustbins, shelves, etc. Surface sprays attack the roach’s nerve function with synthetic pyrethroids, causing paralysis and death.
  • Traps and baits: Traps and baits provide a longer roach control and are effective when used along with a surface spray. They contain indoxacarb that enters into the insects’ nervous system and blocks sodium channels, causing dehydration and death.
  • Knock-down sprays: Knock-down sprays contain similar key active ingredients but help target a single cockroach at a time and eliminate them instantly.
  • Level of toxicity: Check the product label to find the toxic level of the product. If “caution” is mentioned, they are moderately poisonous. In case “poison or dangerously poison” is mentioned, please stay away, cause even a small accident will be fatal. Several kids- and pet-friendly roach killers, such as glue papers, one-way doors, and ultrasonic repellents are less effective and safer than regular roach killing products.
  • Length of efficacy: The length of efficacy defines how long the roach killer’s intensity will work before it requires a replacement. It depends on how much product you apply and how fast the active ingredients break down. Mostly, roach killers will have an efficacy period of one month to two years. Choose the product depending on large or minimal infestation.

Precautions To Take While Using Roach Killers

  • Vacate the treated area after applying the roach control pesticides.
  • Keep foggers away from fire or any ignition sites.
  • Do not overuse foggers or spray.
  • Read the warning instructions carefully before using the pesticides.
  • Place the pesticides away from the reach of children and pets.
