I don’t think it’s an issue of pesticides being “too weak for consumers”. You can buy all the same stuff as an exterminator[0] (use PPE and follow the labeling, don’t break laws, etc), but when you spray you’ll notice a huge knockdown, hundreds will die, but it only takes a breeding pair to get right back to an infestation in a few months. Generally when doing roach infestation treatments you do a multi tiered approach, with max legal mixes of pesticide + growth inhibitors in your spray then putting down bait in spots that you DID NOT spray (or they won’t ingest the bait). They’re just resilient little buggers. Spiders are actually harder to treat, but most people don’t end up with spider infestations. And then bed bugs are in a class of their own in terms of awfulness and difficulty of elimination. [0] https://www.domyown.com https://www.domyown.com

Which roach bait products have you had success with?

I do buy industrial strength pesticides on Amazon but apparently if you were to buy off a reputable supplier you'd need to give your exterminator credentials. I spray Bayer's Polyzone outside and use Tempo between walls/floor and cabinets and see a dead roach inside every quarter or so (there are commercial food establishments nearby so roaches are just roaming the streets). Never bothered with GHI as the pesticides already do a great job.

In Germany you certainly can't. They would outlaw handsoap if they could get away with it.

Thanks for this link and your replies in this thread. As someone who had to feverishly dust boric acid around my kitchen last summer (because in Washington state, it seems many online stores like Amazon don't want to ship anything effective. Maybe regulations?), I'm looking forward to trying out Vendetta Plus or something similar if these German roaches return.

  Incidentally I've actually found "natural" solutions like boric acid and diatomaceous earth to be wildly effective (in killing/reducing established populations, not preventing new ones), if a bit unsightly and inconvenient to have lying around in piles to actually force the critters into crawling into them. I probably ought still spend a day off sealing everything I can, though. Probably more pragmatic and less technically barbaric.

    I would recommend getting an actual duster (aka "hand bellows"), especially one that has an actual spring to return the bellows instead of just a "plastic spring". I learned it from this video [0]. It really helped to basically make the dust small enough for the roaches to scurry through (instead of avoid like a pile). They don't really want to eat it (like bait), so they need to accidentally walk through it and then clean themselves (and incidentally ingest it).
