How to Choose a Roach Killer

Roach poison

There is no specific guide for buying the Roach killers; one has to decide based on the rate of infestation in your apartment.

Infestation Rate

When the infestation rate is low, the roach tablets and roach sprays are quite efficient to handle the situation and eliminate the infestation.

The Roach killer glue bait straps are an herbal alternative to kill the roaches in low infested areas as they are devoid of any toxic chemicals; therefore, they can be used both indoors and outdoors.

High-infested areas require roach killer foggers and aerosol sprays to eliminate the roaches and keep them in control for a more extended period after the application.

The foggers and spray allow destroying the nests and killing the cockroaches hidden in the houses’ deepest regions.


The purchase of a roach killer is dependent on your budget.

The decided budget helps you filter your search and limits your options; this also prevents you from being confused with various options.

The infestation rate also limits your budget plan as the high infestation rates require high-end products like insect pesticides and effective roach foggers, although they are economical.

These insect pesticides and foggers can be used multiple times for years to treat an infestation.

The roach aerosol sprays and roach killer powders are perfect if you have a standard budget; they are the most popular and preferred choices of most households as they are cost-effective and can efficiently kill the roaches.

In case of a low budget, you can opt for the roach tablets and glue straps that are also effective in killing the roaches.

However, they fail to destroy the nests and kill the roaches hiding deep inside the corners of the house.

Type of Reaction

Some of the roach killers can kill the roaches instantly within minutes of contact with the roach killer, while others allow the cockroaches to feed on the bait and carry the poison along with them to the nest where they as well as other roaches die, eventually destroying the nest.

The former is a fast and instantaneous process, whereas the latter is a slow process that may take time more than even weeks.

However, both ways are similarly effective and efficient in exterminating the roaches.
