Hello friends of entomology!
Here's a female opinion regarding the Mauritian cockroach: Stephan is right, it is a flying insect and loves to move around in particular in summertime (so no worries in September); however I feel cleanliness does play a big part in its appearance.
As I'm one of these famous 'German housewives'
you will not find any open food in my kitchen or somewhere else in the house. Food is either in closed lid plastic boxes or in the fridge. Any cocky daring to enter our house is subject to immediate and sudden death (I got really fast since living here - even my husband is scared of me!) or in case I don't get it will painfully starve.
I guess there are some hundred percents more cockies i.e. in New York City than in Mauritius, and as far as I can tell, the NYC species is bigger than the Mauritian one.
Your girlfriend doesn't need to be scared, in particular as you will be staying in a hotel. Have a wonderful holiday on this beautiful island!!!
@Olivier: now how come you know the size of Becks finger? And is this the only part of his body you're familiar with?
