Buyer’s guide to Select the Best Roach killer

1. Choose roach killers that are safe

The best method of finding out about the toxicity of a Roache’s killer is by giving attention to the signal heading at the top of the product tag – it gives you a warning as to how harmful the product is.

No signal directing means the product is quite safe to use.

Caution indicates the product is a low to moderate hazard and could result in irritation to skin or eyes.

POISON is very precarious and can cause poisoning if it penetrates into the body.

DANGEROUS POISON means the product is very hazardous – just a little amount also can cause poisoning or even death if it gets into body.

2. Choose suitable variety of roach killer

There are three main categories of Roach killers: surface sprays, baits/traps, and knockdown sprays.

Surface sprays

Surface sprays give preventative, long-term control. Their active ingredients are synthetic pyrethroids, which interfere with Roach’s nerve function, causing paralysis and ultimately death. Some also contain insect growth control, which works to inhibit the lifecycle of the Roach.

  • Surface sprays are best applied to breaks, crevices, and gaps, as well as inside cabinets, drawers, and shelves.
  • Don’t deal with surfaces where food is dealt, or that are rinsed regularly, with surface spray.
  • If treating food storage regions, ensure food is sealed and discarded first.
  • Always wash hands after usage.

Knockdown sprays

Knockdown sprays, which also use synthetic pyrethroids, target individual Roaches, and provide a quick reaction.


Hope, now you know how to select the best repellent to get rid of roaches, but do keep in mind that don’t stick to one product if it doesn’t show effect for a long time. We suggest, you keep changing the roach killer sprays periodically.
