Why am I finding cockroaches in a clean house?
Finding roaches despite obsessive cleaning usually points to random visitors or neighboring units rather than an internal infestation. These stray encounters spark intense anxiety and contamination fears, leaving people unsure whether to panic or ignore it.

“I've seen probably 7-8 german roaches, adults and nymphs, dead and alive, over the past 17 months in my kitchen.”source ↗
“Where tf are they coming from? I don't think I have an infestation because of the glue trap experiment, and I always spot them months apart from eachother.”source ↗
“I'm super paranoid and not sure if my neighbors are just dirty or I get random visitors.”source ↗
“I moved into my apartment in May. I didn’t have any issues with pests (except termite swarmers that show up every year like a biblical plague) up to this point. In the last month I found a dead roach and a live one during the day. What prompted this post was a baby I found tonight.”source ↗
“I keep a relatively clean apartment; I don’t leave food out, I sweep regularly, I generally don’t keep a lot of dirty dishes in the sink.”source ↗
“Regardless of the cause, what can I do? I’m going to mention it to my complex because we do have pest control that comes twice a month, but I don’t understand how even with pest control and my (at least in my opinion) decent cleanliness habits, I can have enough of an infestation for one to be out during the day.”source ↗
“I grew up in a pretty gross house (lots of kids, pets, and neglectful parents), so I feel pretty lost/overwhelmed when it comes to cleaning sometimes (negative associations). I really just need any relevant cleaning advice because I feel like I’m going crazy.”source ↗
“Im freaking out I grew up in a shelter with roaches and now I finally I bought this apartment in a new building I cant have roaches again”source ↗
“I have found what I am 99% sure is a dead cockroach in my apartment whilst cleaning out my front closet today in my unit.”source ↗
“I have severe contamination ocd so as you can imagine; I often obsessively clean and don’t even leave as much as a microscopic crumb on any surfaces.”source ↗
“I’ve never seen a cockroach in real life before but having them has always been my biggest fear.”source ↗
“Anyways, sorry for the long ramble I just am hoping for someone here to alleviate my fears— or at least be honest and tell me what my next course of action should be.”source ↗
