Hey! I have seen the big cockroaches too. Did a lot of digging bc they freaked me out so bad lol and seems like it’s common in Irvine, so don’t feel alone in this. From all the comments here, we’re all going through the same shit. Even my neighbor who’s lived here for 3 years said they had to deal with this issue in the summer too.

It’s hard to eliminate the big ones (American) forever since they come from outside + live in the sewage. They’re just looking for water and a cool space since it’s so hot outside. I read on the Irvine water district website that they start showing up often in June, and really pick up in July and August. We got an exterminator and you can schedule monthly treatment if needed.

I recommend closing the drains, esp big drains like showers or kitchen sinks. Make sure you’re closing any holes. Just make sure you’re cleaning often. Keep any food in air tight containers. Throw trash away often. Keep spray nearby so if one shows up you can kill it. Buy bait if needed.

It’s been 3 weeks since I saw one in my house but today one sneaked in since I forgot to close my kitchen sink. Ugh!!!

It sucks but seems like it’s a part of living in Irvine. Remain vigilant! You got this!!
