Is it true that houseflys throwup everytime they land on something?

Question

OH thats dirty iv got them all over the house in summer

Answer 1

i thought it was. but is it..?

Answer 2

Yes, this is true. House flies have a constant diet, so either they are releasing fecal matter, or they are releasing digestive fluids. The fluid is a way for them to soften hard, solid matter, then eat it. Disgusting, I know. It is why they are so dangerously known for carrying diseases.

Answer 3

We've got stomachs & digestive systems, so we eat our food & digest it afterwards.

Flies are little things who haven't got room for all that weight, so they pour digestive juices over their food, wait for a bit & suck all that yummy goodness up.

Wanna know what's really ucky?

Rabbits don't have enough room inside them for all the digestive system needed to digest grass, so after it's gone through them once, they eat it again.

So yes.

Answer 4

I thought they crapt every 3 sec on something.

Answer 5

Flies excreet digestive juices onto whatever they land on as a method to taste it before they start eating it. So I suppose the answer is yes.

Answer 6

No they p**p.

Answer 7

Only if they plan on eating it.. Spitting up on it causes it to basically start breaking down so they can suck it into their stomach.  It's the same as chewing your food..  Did you know that human spit also has digestive qualities?  Flies don't have teeth, though.. so they can't chew their food to break it down.
