Firstly, this is what fly eggs look like.
They must be removed immediately. Every last one.
They will hatch out into maggots which will essentially begin to eat the creature the eggs have been laid on.
This really cannot wait and you must either get the creature to a rescue centre, a vet or remove them yourself immediately.
If you cannot make it to a vet/rescue centre quickly and you have to do it yourself you will need tweezers, warm water and patience. You can add a little skin-safe antiseptic to the water if you have it.
Wear gloves, and use the tweezers to remove the clusters of eggs. Rinse the tweezers in the warm water to remove the eggs, dry on a paper towel and just keep going until they are all gone.
Check eyes, ears, nose, mouth, genitals and between toes carefully.
Sometimes an old toothbrush or flea comb can help here if you have them.
Work in short bursts, keeping the creature warm as you go with a hot water bottle and warm towels.
Flies will not lay eggs on a fit creature. There is always a cause, which is why we recommend taking the creature to a rescue/ vet once the eggs are off. If there is no apparent wound the chances are it is a severe problem such as hypothermia, parasite overload, poisoning, starvation which has to be treated either at a vet or sanctuary.
If there is a wound and the creature seems fit and well, then it is straight forward, clean, disinfect and barrier the wound. Keep it clean, fresh and dry until it heals. Savlon is an excellent wound wash and Flies hate sudocrem, it's great stuff for superficial wounds, it is cheap, people tend to have it in their homes or their neighbors have some.
If a wound is running with pus, blood, sticky fluid or looks angry red, swollen, smells bad or it needs stitching, it is best NOT to apply anything to it other than an antiseptic wound wash such as savlon and get it to the vet/rescue right away. Don't obscure the wound with thick creams etc. The chances are it will need antibiotics too.
