Yes, killing a roach can attract more roaches. When a cockroach dies, it releases oleic acid, which can signal other roaches to the area – effectively a roach distress call. Moreover, the decaying body can serve as a food source for them, further attracting them. Thus, it's important to promptly clean up after dealing with cockroaches in your home to prevent attracting more of them. Regularly dispose of garbage, clean spills and crumbs immediately, and seal food containers to mitigate roach infestations.
