why do c0ckroaches flip when they die?
-
er... anybody knows? i have been seriously wondering about this for some time now. and having killed a bloody roach today, i am really intrigued.

balance.. if it's on its feet, it's top-heavy.. so when i kicks it, no more movements to keep it on its feet.. the legs are lighter than the body so it flips over...
-
no leh.
when u squash them, they dont flip.
all the juice will squirt out.

when they die...hydrogen will form in their stomach
since hydrogen is light but cannot escape...they flip -

sometimes u can see the brain matter. -
nope, this doesnt make sense. they are still alive and kicking (quite literally, u realise) when they flip.Originally posted by thoreldan:when they die...hydrogen will form in their stomach

this makes more sense... but er... why will it kick in the first place? if a live c0ckroach flips on its back, can it right itself again?Originally posted by the Bear:balance.. if it's on its feet, it's top-heavy.. so when i kicks it, no more movements to keep it on its feet.. the legs are lighter than the body so it flips over... -
u have been thrice warned.
EVEN more RHK nonsense in your forum. -
very hard.Originally posted by starblue:this makes more sense... but er... why will it kick in the first place? if a live c0ckroach flips on its back, can it right itself again?
cos now the body, which is heavy is at the bottom.
and the legs in the air.
maybe it can flip the back, use the wings as a lever and push it upright. -
Actually hor very simple de , is because its a natural reflex action like when you kana attacked , naturally you will turn over and see who your attacker is right . So since cockroach head cannot turn all the way back so usually they try to run or fly as fast as possible untill they know they sure die liao then flip over so as to know who their attacker is ma , so that when they reach Huang Quan Lu , at least they know who killed them and who to go after lor , so they die die must make one last attempt to flip over to see your damm face before they die ma .
does my answer make sense ? -
lolz... u... dun encounter c0ckroaches very often do u???Originally posted by seotiblizzard:very hard.

when someone whacks a roach, but only succeeds in turning it on its back.... it.... totally just flips itself back up and scurries away, doesnt it? when have u seen an intact roach helpless on its back? -

i tink its more psychological.. maybe coz the sight of overturned cockroaches more grotesque than the normal face, then the impression of overturned cockroaches get stuck in ur mind more..?
afterall the chances of flipping and not are 50-50.. well, thats just my guess.. -
u see the roaches leg quite short
after u spray pesticide , i think it feel the toxic and pain
then i start to jump around , after jump if it landed leg down , i still can jump again by pushing it leg up.
When it at overturned position , the leg is too short and the roaches back is too smooth to turn around , so the leg is able to do a jumping action but leg touch air only ,
more attemp = more tries ,
more tries = more time
more time = toxic spread = mati -
"Why do most cockroaches die on their backs?
"First, few cockroaches die on their backs in the wild. Natural death of cockroaches probably occurs in the stomach of a bird, bat or other small animal.
"Second, Cockroaches are not used to living on a polished marble or vinyl floor. They are more used to a ruguous living plane including leaves and sticks and other vegetable debris. Thus when a cockroach finds itself on its back (by some mistake in its orienteering) it may have trouble righting itself if there is not debris around to grab hold of with its legs. (Try it, put a cockroach on its back on a polished floor with and without some crinkled paper.)
"Third, often we come across dead cockroaches in buildings that have died of insecticide. Most of these insecticides are organophosphate nerve poisons. The nerve poison often inhibits cholinesterase, an enzyme that breaks down acetylcholine (ACh), a neurotransmitter. With extra ACh in the nervous system, the cockroach has muscular spasms which often result in the cockroach flipping on its back. Without muscular coordination the cockroach cannot right itself and eventually dies in its upside down-position." -
i hate botak plus c0ckroaches

just like fish lor..

oh yah!! why didnt i think about how disrupted muscular coordination will disallow the c0ckroach's maneuvre??!Originally posted by ^tamago^:"Why do most cockroaches die on their backs?

oh fuk! it all comes together.... no wonder after the first few seconds the spray hits the big c0ckroach, it flipped and kicked air for a bit, then it righted itself and continued scurrying off. i had to quickly spray some more... then after that it cannot flip back onto its legs le...
yah hor!!!!
thanks! -
They want to face heaven for the last time.
But some cockroaches don't flip when they die leh. Especially when they got splat with my slipper. -
yeapz thats right! someone did his homework!
Basically, cockroaches die because they are flipped. -
Insecticide need to spray quite long... at least 5 secs..
Dettol and Listerine = 2 secs
Kiwi Floor Cleaner = 1 sec
Wack = 0.5 sec
