24 hours so why are there still so many in my kitchen?

Q: What's the scientific name for the little
beggars?
A: In North America, the most common variety is Drosophila Melanogaster.
Non-scientifically, they're also commonly called "vinegar flies".
Q: How long do they live? I've heard it's only
24 hours so why are there still so many in my kitchen?
A: They live for about 30 days. This means they might hang around your
house this long, even without somewhere to lay eggs. Their actual lifespan
varies with the temperature. They live shortest but breed fastest at higher
temperatures, and live a long time but breed slower at colder temperatures.
They multiply fastest at 86 degrees Fahrenheit / 30 degrees Celsius.
Q: How did they get into my house? Did I buy "infested"
fruit?
A: Contrary to popular belief, most fruit flies DON'T "come home with
the fruit". They find their way into your house later as the fruit ripens
and the smell attracts them through open windows, doors, cracks, etc.
Q: How do I know if the swarm in my house
is fruit flies?
A: They're flies, they're tiny, and they have red eyes. They'll hang
around fruit or other attractants and multiply like mad. You'll notice
a few and a week later you'll have hundreds, soon to be thousands.
Q: Fruit is obvious, but what else do fruit
flies like?
A: They are attracted to fermenting fruit (eg. yeast), baked goods, alcohol
(eg. wine), vinegar, rotting vegetables, fruit juice, lemon scented detergent,
fruit scented bathroom products, bright light, the colour yellow, and
reflective surfaces. Ounce for ounce though, our own (patent pending)
Dead Easy bait is the best attractant we've found.
Q: Is there anything unusual about fruit flies
I might find interesting?
A: Fruit flies can metabolize alcohol fumes. Yes, FUMES. While they obviously
can't lay eggs in a gas, they are able to "eat" the fumes to subsist.
A: Fruit flies can be addicted to crack cocaine. When "high", they groom
obsessively, and walk sideways and backwards (which they never do naturally).
Dead Easy did NOT conduct that research.
A: Fruit flies are the critter most used for genetic research worldwide.
A: Fruit flies learn some functions better without a head. Yes, that's
right, decapitated.
