I think the last time I saw a cockroach here in London was in East London many many.. years back, but health inspectors have found cockroach infested homes that were un-kept & filthy, often by sick & elderly who can't clean, while some people are just filthy. Very important to stay clean & hygenic. Cleaninless can ward of many bugs. East London is a filthy hole anyway. In fact all of London is filthy! Came back from Dublin recently, which used to be filthy, but it was fully clean, no litter lying anywhere. We have a MASSIVE..!! rat population here in London. Just walked by a big rat earlier tonight. We've too many rats!

I've heard from Brazilians how advanced Brazil is, even more so than here in many respects, with more personal freedoms, & have been reassured there are no big spiders in the urban populated centres. I'd just keep away from the jungle then, unless I'm covered in a beehive protective suit. I jumped on a wasp nest once as a kid, got stung from head to toe by the little bastards, so not very keen on wasps either.
