They come from open junction box on kitchen wall, and they spotted around fridge. Recently been seeing one or two in bedrooms. I think its because I sprayed Raid in the kitchen. This been going around for a month or more now. The type looks to be german cockroaches. Where I live there arnt known brand pest control products to use, and the ones that are available dont always list their ingredients. So what natural everyday things I can find that can kill them once and for all? I put generic bait around the fridge, but I still see them now in other places. To stop them from getting into bedrooms, i spray Raid on the floor.
I have had great luck with boric acid based products for ants and roaches and just about any bug. It's inexpensive, effective, and relatively safe. It's easy to dust in the cracks and crevasses and gaps and spaces where they hide.
Diatomaceous earth is another alternative that I have heard is just as safe and effective, but boric acid has worked so well I haven't bothered to try it.
I've heard that hot sauce or anything spicy hot will deter them. There is also electronic repellants that produce radio waves on a frequency that they cannot stand that they'll run from. But make sure that it's a good brand and one that can penetrate through walls
Natural solution that helped me was spiders. They love eating them. Aside from that, you need to find their nests which is easily identified by their droppings beneath and kill them. Typical nest locations are dark, warm areas such as near hot water pipes under the sink. Kill the eggs as well. Good luck!
