How To Choose The Best Roach Killer For Your Home

With the wide variety of cockroach killers in the market, which one should you pick? We’ve shared that they commonly come in sprays, traps, baits and ultrasonic repellers. Each one functions differently and has their own strengths weaknesses.

1. Location 

Cockroaches like to lodge in dark, moist and unreachable places. In the kitchen, they are normally under the sink and in the cabinets. In the living room and bedroom, they love dwelling behind hanged wall arts, in the closet and under the bed.

Sprays, gel baits, powder and electronic roach killers can ward off cockroaches even in the narrowest passages. While traps and baits in casing must be strategically located in infested areas. Traps will also work best if you are trying to identify the breeding ground of pests and can be easily transferred to a different location in case who have not attracted any in a day or two.

There are cockroach killers that can be used indoors only like some gel baits, traps and ultrasonic repellers.

2. Severity of Infestation 

Not all cockroach killers have the same formulation. Just like medicines, the degree of potency will address the severity of the infestation in your home. Traps, baits, sprays and insect growth regulators in different forms can be used standalone or it can be combined for optimum results on heavily infested locations.

3. Ease of Use 

Sprays, baits and electronic roach killers are the easiest to use among the cockroach killers in the market and can be used instantly fresh off the box. Some gel and liquid baits will require a little effort to prepare and dispense.

4. Duration of the Effect 

The need for re-application is an overlooked characteristic of a roach killer. It can contribute to the price and ease of use factor if it needs frequent re-application. Sprays normally have a 4 to 6 months effect, gel baits are reliable from 6 months to 1 year and most traps have a 12-month efficacy although it will surely look nasty over time.

5. Environmental and Health Hazards 

This is the most important consideration in choosing a cockroach killer. Cockroach droppings are known allergy and asthma triggers. But the fumes from the sprays and gel baits do not fall short as an environmental and health hazards. Read the labels and make sure to follow the directions to use.

6. User Reviews 

These are very important sources of information. Check out the pros and cons thoroughly, watch unboxing videos, and check out photos of the actual results. User reviews would surely tell you bits and pieces of information similar to this guide to let you assess which one works best for your need.
