Although you can kill a cockroach using several methods, not all are the same and effective. Some will land you in hot water by attracting a roach colony towards itself. Therefore, not every method recommended on the internet is the solution to a roach infestation.
Killing a cockroach by squashing or by applying a force attracts more roaches and other insects towards itself. This is because a squashed roach releases a number of pheromones, including oleic acid, that attract insects along with roaches.
Have you wondered about a stenchy fluid on the surface when you squash or forcefully kill a cockroach? The fluid is difficult to clean because it contains body juices and oily substances called oleic acid. Oleic acid is the reason for the smell, often called the stench of death.

Why Does killing a cockroach attract more?
Killing a cockroach does not always attract more roaches. Instead, it is depended on the method being used. For example, killing a cockroach using bait or insecticide spray will never attract roaches. Instead, the bait will kill more roaches, whereas the smell of insecticide spray will repel roaches.
However, this is not the case when you squash or forcefully kill a roach. Squashing a cockroach to death releases body juices along with stress pheromones. These pheromones contain a derivative of fatty acid called oleic acid.
Oleic acid has the property of attracting decomposers, including roaches. This signaling helps roaches locate a source of food, helping roaches thrive.
However, once you squash a cockroach to death and dispose of it safely, it will never attract other roaches.
In short, a dead cockroach attracts other roaches when you kill them by squashing. Otherwise, it’s not always the case.

Stopping A Dead Roach from Attracting Other Roaches?
Nothing is more distressing than finding a colony of roaches attracted by a dead roach that you killed, thinking you will prevent an impending infestation.
However, you don’t need to worry because you can quickly stop a dead roach from attracting other roaches by following methods,
Method 1: Killing roaches with baits
This is probably the safest method to prevent dead roaches from attracting others. All you need to do is mix two parts of boric acid with sugar and sprinkle it around the corners. Once cockroaches consume it, they share it with other members and help kill them.
This will not only kill roaches but also prevent attracting other roaches.
Method 2: Using roach bombs
Roach bombs will help you instantaneously kill all roaches all at once. In addition, the smell of roach bombs prevents other roaches from getting attracted.
Method 3: Disposing of roaches properly
If you have killed a roach by squashing it, you must dispose of it properly and clean the surface with detergent to remove the oleic acid from the surface. Once the surface is clean, you don’t have to worry.
