Coupled with the effectiveness of the product, this has caused people to set off repeated bug bombs. Even worse, as Koehler explained, is that there have been cases where people haven’t properly sized the amount to the room size. Koehler explained that because there is little to no air circulation in the small spaces where roaches reside, the insecticide won’t reach them. This is a blanket treatment that is set off in an unoccupied room on the theory that the space fills with insecticide and kills off the roaches. Total release foggers (aka bug bombs), such as the Harris Indoor Fogger, are another category we dismissed without testing. Each little canister has roughly 150 bait applications in it, so you can bait in a lot of different places, increasing your chances of success. The Terro bait powder is also a very economical choice if you’re dealing with a larger infestation or if you might be dealing with roaches in the long term. One thing we appreciated in testing is that a powder won’t get all goopy if you accidentally put your hand in it or rub up against it. Other powders we tried come in larger squeeze bottles and are much harder to portion out in small amounts. The applicator nozzle is very precise and good for getting into hard-to-reach areas, like under the fridge. This powder bait comes in a pump dispenser with a 2-inch-long applicator, and each pump dispenses less than 1/16th of a teaspoon of bait powder. And though it’s not quite as neat as a bait station and isn’t able to stick to a vertical surface, it’s effective if you can apply it right where roaches are living. The Terro T530 Roach Bait Powder is another option.

Gels are effective too, but the enclosed Terro station has far less potential to be messy or accidentally consumed by a pet or child. This way you can place the bait station close to where roaches are living. The Terro stations are also one of the few that come with adhesive strips, so they can be mounted on a vertical surface. The top of the bait station is clear, so it’s easy to monitor how much bait is left and whether the roaches are even entering in the first place. The Terro bait stations have a number of features most roach baits lack, which make them the most convenient and easy-to-use option we’ve found. The delayed action of the poison increases its overall effectiveness, since it allows a roach to pass the poison to other roaches before the roach dies (and even afterward if you want to go straight to the disgusting details on how that works, be our guest). The Terro T500 Multi-Surface Roach Baits are little cartridges filled with an insect bait-a mixture of food and a slow-acting poison.
