Lizards don't bother me so long as they don't crawl under the covers and snuggle up to me. PB, I understand where you're coming from but I don't personally mind insecticides for a week in paradise. LOL
Like I said, I've been to the Caribbean several times and I'd like to keep up my track record of never knowingly sharing a room with a roach. I would never expect any island/city/restaurant to be totally bug free. I just don't want to share my bed/plate/shower with them.
