Not much info I could find on what surfaces do cockroaches are unable to climb - nor I have read much into their precise methods of how do they climb stuff, however on this website: https://www.terminix.com/blog/bug-facts/can-cockroaches-climb/ they mention that the following give cockroaches a hard time climbing: Porcelain, Glass, Smooth metal, Granite, Marble surfaces.

So from what I gathered two things came up to me on how to prevent these bastards to climb onto something, in my case - I don't want them to climb up on my bed.

1.) Coat a slippery surface on my normal surface (bed legs, however I don't have bed legs as I have a box bed).

2.) Spray the bed legs (better if you have box bed) with a repellent like pepermint or eucalyptus, which btw I have no idea how effective these are at all or how long do they last, as the sources where I read this weren't really factual.

Do you guys know any other way on how to prevent them climbing on my bed? If method 1 is ok, what material should I use - I thought of wrapping up transperent tape around my bed but not sure if that counts as slippery. I know it will look terrible, but the crawl of a cockroach shell waking you up and presenting itself to you is far worse image than anything else and a far worse nightmare than the one you were waken up from. I thought about sticking some other material to it, but I really don't know what will work - I have oriental cockroaches why do not fly. Also if anyone tried method 2, is this legit, how long does the effect last for?

Thanks.

  • They can also fly short distances. The only way I know is to kill them before they can climb on your bed. Oops I missed you have the ones that don’t fly, do they jump? – Ed Beal Oct 7 '19 at 21:17
  • you can make a moat around each leg with a salad bowl. you really should kill them off though, boric acid works wonders for that; cheap and harmless to pets. – dandavis Oct 7 '19 at 21:54
  • @EdBeal Yeah, oriental are supposed to not be very fly-ledgable, I think they don't jump either. I know, however while I sleep I can't kill them before they come in. – appwizcpl Oct 7 '19 at 22:38
  • @dandavis Boric acid is fine (think is not for cats, not sure thought however I don't have any). – appwizcpl Oct 7 '19 at 22:39

I had a client who had the same problem with the box bed. I put two wraps of foil tape around the frame and it kept those little bast...ds from climbing up. You have to make sure the surface is really smooth and kink free. You can pick up this tape at any home store.

Also, try to bug proof your place. Check for openings around drain and water pipes. Place a few of those "Roach Motels" around the place to kill off some that might already be in. Other than spraying insecticide, which many people don't want to do, I don't know anything else to do. There's a reason they've been around since before the dinosaurs and have survived. Good luck.

  • (1/2) Woah, didn't know that dino fact. By foil tape you mean this: i.imgur.com/kiPxdbK.png? I don't think I have ever seen that in my life, at least in Europe. Yesterday was a scary day, I found their place if I can call it that, but basically from a drain that is under my sink. I caught one and I sprayed her with raid, she ran there I sprayed there, nightmare afterwards. Roaches kept swarming (not much 1-2 per time) toward anywhere but there, luckily they not that large, and only one was medium sized. So I think they are coming from the sewed, however not sure how - I think.. – appwizcpl Oct 7 '19 at 22:44
  • (2/2) ... the p-trap there is fine, no smell no nothing - do they swim up?? I am not sure what happens, ventilation, manhole - not sure. I have a lot of other cracks too, I took silicone today and I will caulk everything up, cracks at walll and floor, door frames, everything. Not sure if I should use gel before closing the holes or something like Boric and then just seal it off for good. I also am planning to put some gels on the drains on the floor, close it off with a transperent plastic cup/plate and try to see what happens. The thing is if they come from the sewer, am I screwed? – appwizcpl Oct 7 '19 at 22:49

    If you found where they are coming in I would try and find the foil tape we use it in air ducts on this side of the pond so a hvac/r supplier may have it. The tough part is killing them off once inside. I have read they can survive on a scrap of news paper or any kind of food waste. They say after a nuclear war roaches will be one of the few critters that can survive.+ – Ed Beal Oct 8 '19 at 13:40

    just keep smoothing it out as you apply it.. no air bubbles or kinks. Here's what I used: amazon.com/ATack-Aluminum-Reflective-Furnace-metalworks/dp/… – JACK Oct 8 '19 at 15:51
