My hamster very like to eat "kuaci" 
2 of them always fight will the "kuaci" 

ya ~ maybe flat floor is cool then wood shaving ~
my hamster also sleep in flat floor  ...

RIP 
red ants really ...... 

u got put any food ( sweet 1 ) to feed hamster ?
maybe red ants come because of the food 

Red ants are attracted to any left over food in the tank or cage.... when it sees that the food is not edible for ants, then they attack the next thing in the cage, the hamster. Red ants do not care the hamster alive or dead, to them, it is another mean of food. Never place cages on floors, best is on tables. If prone to ant attacks, get ant poison.

i think is kacang 

feed the kacang or fruit when u are here ~
before u gone then clean the box that u feed them "sweet" food ~
because hamster mix food normally would eat by red ants 1 ~

Have you stepped on red ant nest before? I did.... and they bite.... you know why they bite? Coz I stepped on their nest, kacau them....

I am guessing your female kinda kacau the red ants when they entered the cage.... so when 1 red ant bites, another will bite... then chemical signals will tell all ants to bite. Your other hamster is safe due to maybe never interfere.

Another scenario would be your hamster died from unknown reasons so the red ants out of nature attracted to the body and try to eat it.... still... red ants... ai, they are a pest.

Sometimes they simply come. I got some hamster cages that got black ants and I dunno where they come from but black ants are not so fierce and my hamsters ignore them.

What you can do is place some ant poison lah. Or repellant. I use repellant coz safer. I think you can find those in certain hardware stores like Ace...

may it RIP..
there are no red ants in my room..
but i looked "semut halus" there..
i found there nest, then .....
