@Gwen386 lol, cos ants only arrive on the same day?
we do back to backs all the time and if anything, that helps to avoid surprise bug infestations.
Last week our cottage was empty for 2 nights, we didnt' do the vacuum/mop until the day of guest arrival, and we found a LOT of dead tiny slugs (not sure what these are called, tiny slugs that leave silver trails over your floors and can enter/leave via fly screens). I've seen them before but it's clear when the cottage is empty -even for 2 nights- the bugs call a house party.
but otherwise agree that cleaners have little control over what the local ant community decides to do today.
and some princess guest cancelling due to ants, good grief. get a cloth and wipe them away. Humans are aware we share the planet with insects, right? I pray I never encounter Australians who ever do such a thing. I will probably grant them a refund and then be a total unprofessional d**K and tell them to hand over their passport too.
