Hello everyone I just wanted to hop on and ask if baby flies are bad for guinea pigs
Hi!
The vast majority of flies are harmless to guinea pigs although they can be a nuisance if you have a bunch of eggs hatching in the cage/hutch.
There are a very few varieties of larger flies (bluebottles and horse flies) that lay their eggs into the flesh of mammals for the emerging maggots to eat. This is called 'fly strike'. Affected are generally only the very frail/old or ill animals with open sores or that cannot clean themselves well anymore. Healthy animals (including piggies) won't be in danger.
Daily poo patrol, regular and ideally twice weekly cleaning plus the occasional deep clean with a stronger disinfectant; being careful with older/frail piggies outside (bum and paw wash before putting them outside and checking them carefully when bringing inside again; fly strips, electric fly catchers and mosquito netting for a hutch; bringing any older or ill piggies indoors can all help to mimise the risk.
Please do not use any sprays around guinea pigs. Many insect sprays contain substances that are harmful and in some cases lethal for guinea pigs.
Fly strike is comparatively rare in well kept piggies but it can happen even with the best of care - if you are unlucky, even indoors.
Here is more information on it, including what you need to look out for and what to do in the case of fly strike:
