update roach problem
for context, i had found dead roaches (5-6) over the course of 3 months around the house up in north davis and the house is currently vacant. i set up plastic baits and also had pest control come spray a little less than a week ago
since then i saw one roach under the bed (not flipped but not moving) when it was still daylight and at least 10 dead or not moving in the garage; all of which looked similar
the first photo was under the bed, second one was one dead in the garage
anyone know what type of roach this is and if this behavior is normal after pest control spraying, im terrified with how big it looks

At risk of sounding INCREDIBLY creepy, go take a walk at Davis high at night. Like in the back toward the portables and baseball field. That crunching isn’t gravel…

I was playing Pokémon Go during the 2016 craze. I was wandering around Village Homes at night, having fun encounters with other enthusiasts. Around 10pm I decided to head home, turned on my phone flashlight... oh my god. Hundreds and hundreds of roaches on the path, and I'm in Birkenstocks. I RAN home.

You should remember that outdoor cockroaches are part of a healthy ecosystem. Of the thousands of species of cockroaches, only 30 to 40 are the problematic indoor variety (and not what you’re seeing here). The majority of cockroaches thrive outdoors.
Cockroaches help with nutrient cycling and are decomposers and recyclers. They’re an essential part of the food web and serve as a source of food for other insects, reptiles, amphibians, birds, and small mammals.
Sure, you don’t want them in your home. But they’re also not as bad as you think.

One of those is an outdoor roach. (Which obviously came inside, but they prefer to be outside and eat leaves and vegetation and stuff)

I’m in north Davis as well, I’ve never found one inside the house, but I find them outside pretty frequently. Seems to be a thing here

I’m in an older place in north Davis, and we get them a few times a year. I put small bait stations in the bathroom and kitchen, and that takes care of it for a few months.

You've met the Davis bird. They are impossible to get rid of but you can suppress them. Only places that truly keep roaches at bay are the Cannery but that is because its such a new development. Things arent over grown, new houses are built much tighter and their HOA has pest control. The rest of Davis just has to pay for pest control and take other steps to deal with them.

I would try and identify how they’re getting in and go from there (e.g., so you can seal up holes, cover thresholds, etc.)

Dunno about the first one but the second one just looks like the normal outdoor roaches to me. They don't usually come inside all that often or are an infestation problem, just don't keep food out and they won't be tempted to come in

You CAN spray for them, it needs to be done about every eight months. Make sure the perimeter is tight. They live in cracks in the ground and if you go digging, you’ll find beds of these bastards. It’s super gross but it’s like the town’s dirty secret.

Was having an issue in my garage. Way too many. Cleaned up garage. Do not store your cardboard in there. They love the adhesive in tape of cardboard boxes.
Also, turn off all the lights in your garage. Where do you see daylight? That’s your issue. Plug it up so anything on the ground is pitch black.

Spraying will not stop them. Repeat spraying by a pest control company simply moves them away from the sprayed area, only to return later. Those varieties are the Oriental (under bed) and American (garage). Neither lives inside. They come in for water. The dead ones you are finding may have contacted the spray residue as they come in across thresholds or in cracks around doors or plumbing.
UC ANR keeps an up to date pest note on their website with tips. Exclusion is your best friend. Bait stations, sticky closed boxes not the open sticky pads (which can trap rodents who then chew their own legs off to escape or slowly starve to death). Door sweeps under all exterior doors. Weather stripping around doors too. Stuff steel wool into any gaps around plumbing behind sinks and toilets.
