Can A Cockroach Smell A Grain Of Sugar From A Mile Away?

I heard this a friend…..
Is this true? what are the possible outcomes of a cockroach using this for their advantage in other ways….wtf that made no sense at all….if it’s true then nothing will change of course but what does this mean is what I’m saying, it has to mean something right?

    oh, I don’t know about the “grain of sugar”, but I did learn something about their “since of smell” (if you want to call it that), from a documentary on TV a while back.
    It seems that scientist are working on various “baits” for roaches and one of these is the “chemical aroma” given off by the female roach when she is ready to “hook-up”. She climbs to a high spot so that the chemical attractant she emits can be picked up by the males. (Ever wonder why you find those big fat females up on the wall near the ceiling. They certainly would not be looking for sugar/food up there.) I forgot the range by which the male can sense this attractant, but, I do remember that I thought it to be an unbelievable distance. Are there any “experts” out there who can enlighten us on this subject?

    well im sure that there will never be a mile radius around a cockroach where there is no sugar so this sounds like a myth.

    Yes Cockroaches, like all insects, breathe through a system of tubes called tracheae and these are lined with cells that can “smell or sense” sweet and sour” things extreme distances away and also “sense” radiation….if you were to use a microwave they would all flee in fear..weird

    first of all, sugar has no odour
    secondly cockroaches have ho organ developed for the sense of smell, so forget sugar, cockroaches cant smell

    Grain sugar is extremely hydrophilic, meaning it has a strong affinity for water. It doesn’t emit a smell, because to emit a smell, pieces of the sugar have to be carried away into the air. This is usually caused by liquid carrying away the smelly molecules as it evaporates. Sugar, however, absorbs moisture from the air. Nor does it float away unless it’s finely-ground.
    A single grain of sugar would not be detectable by a cockroach at a distance of 1 meter, much less 1 mile.

    Cockroaches can smell – But no, Cockroaches cannot smell that far away.
    Cockroaches primarily detect smell with their antenna, but can also detect smell with their mouth.
    However, they do have an amazing sense of detecting movement – They can detect movement as small as two thousand times the diameter of an atom.
