How long will water fleas last in the same jar of water?
360409
They should last a long time as long as they have food, it wouldn't hurt to keep the jar in the light of a window to encourage the growth of algae (in the water not on the sides of the jar). And as long as their waste products don't encourage the growth of detrimental bacteria, a change of water wouldn't hurt now and again (use water that has set out for several days) if their water ever becomes cloudy or keep them cool to discourage bacterial growth. The best way to feed them is to keep a separate aquarium in direct sunlight that is growing a thick culture of green unicellular algae and taking some of this algae (1-2 oz) each day to feed the daphnia. The aquarium should produce the algal culture without seeding after a week or so if it's kept in bright light.

It depends what is being evaluated. In drug testing, urine can be kept for a long time, years even.  For all testing, if it is stored properly - long periods may elapse as well.  If the pourpose is to evaluate for infection - immediate evaluation (same day or 24 hours) is best.

God made them. As long as dirt has been! Nasty little pieces of filth aren't they? Did you know they can live without their heads for 2 wks? I awould not wolf you my friend! Scientific fact from observation by a very honorable institution came up with this scary fact. So get some boric acid and sprinkle a line around your baseboards and the back of your countertop around your trash can around fridge, any where they will have to walk across it, even put it across the window sill and on the floor threshold and wait patiently always keeping the lines full of boric acid and after a while they will kinda disappear, but if you live in town keep the boric acid out all the time because they travel well and love to see new places.

Fleas pass through a complete life cycle consisting of egg, larva, pupa and adult. A typical flea population consists of 50 percent eggs, 35 percent larvae, 10 percent pupae and 5 percent adults. Completion of the life cycle from egg to adult varies from two weeks to eight months depending on the temperature, humidity, food, and species. Normally after a blood meal, the female flea lays about 15 to 20 eggs per day up to 600 in a lifetime usually on the host (dogs, cats, rats, rabbits, mice, squirrels, chipmunks, raccoons, opossums, foxes, chickens, humans, etc.). Eggs loosely laid in the hair coat, drop out most anywhere especially where the host rests, sleeps or nests (rugs, carpets, upholstered furniture, cat or dog boxes, kennels, sand boxes, etc.). Eggs hatch in two days to two weeks into larvae found indoors in floor cracks & crevices, along baseboards, under rug edges and in furniture or beds. Outdoor development occurs in sandy gravel soils (moist sand boxes, dirt crawlspace under the house, under shrubs, etc.) where the pet may rest or sleep. Sand and gravel are very suitable for larval development which is the reason fleas are erroneously called "sand fleas."\n\nThey do look like little worms when they are in the larvae stage.  Very little worms.

Hello!\nI don't mean to answer a question with a question initially, but are you sure it was a flea?  (Just curious)\n\nI recently had issues with fleas here in my apartment because of a neighbor who brought in a stray, flea infested, dog.\n\nI was bit all over my feet and ankles for about a month till we got the problem under control.  It was AWFUL!\n\nFlea bites itch like mad, of course.  Definitely competition for Mesquito bites.  LOL\n\nIF you take the steps to help keep your flea bite from itching rather than scratching at it, you'll heal within 2 weeks.   If you keep aggrivating it by scratching it, you'll damage your skin further and it'll take longer, of course.\n\nThere's really good Cortizone creams out there that you can get over the counter that help with the itch.   I bought Cortaid Advanced for me because I have a health condition that causes bites to itch much worse than normal so I got INSANE if I get bit by something that makes me itch. \n\nThe Cortaid Advanced lasts 24 hours (give or take a few hours depending on how sensative you are).\n\nKeep in mind, also, that unless you get some form of pest control, you'll be bit over and over again and fleas DO multiply quite rapidly.\n\nWe had to have a professional pest control company come in and saturate our carpets and spray all around our apartments to get the fleas under control.  Even then they're not completely gone, I still get bit from time to time.\n\nI ask if you're sure it's a flea that bit you because generally they do bite on the feet and ankles and it's likely you'd have numerous bites.\n\nGood luck to you!  Hope ya heal up quick :)

Get one of those bug bombs, and leave for a few hours.  If you have pets you should move them somewhere else.  I know, take them on a road trip with you?  Even the goldfish.

Be careful with the all natural flea medication.  I got some called natural chemistry it poisoned my cats.  I have 5 white cats it turned them orange and they got really sick the day after I sprayed them.  I had to take them all to the vets they had severe vomiting and diarrhea. They had to stay at the vets for 4 days they were so severely dehydrated and poisoned.  Instead of saving some money it cost me $800.00 and one of my cats.

If the medication was stored in the container in which it was received in an indoor cabinet but not in the bathroom medical study suggests that nearly all medications retain nearly all of their potency for at least 5 years after their expiration date.  I hope that your headache goes away.

Depends on a number of circumstances.  \n\nTemperature and humidity are the main ones.  \n\nIf it's hot and moist, then there will be plenty of decomposition, lots of bacterial action and scavenging by insects such as flies (maggots) and beetles.  It could take as little as a few days for everything to be gone.\n\nIf it's hot and dry, then the dead kitties may dry out and stop stinking long before they disintegrate, leaving little mummified kittens under your house.  You may not want to think too much about that possibility.\n\nIf it is very cold, then the kitties will freeze and be preserved, until spring time when they thaw out and start stinking again.\n\nIf it is just moderately warm, even cool, and moderately dry, then they could take weeks or months before they've rotted enough to stop stinking.  Presumably the mother cat was able to get under there to give birth, so there's probably access for insects, and that should help speed the process.\n\nDon't spray Raid or use other methods that will discourage insects from the area.  You'll want their help in breaking the bodies down as quickly as possible.  Depending on where exactly the bodies are, you may end up with a brief infestation of blow flies, dermestid beetles or other insects afterwards, but that will die down unless there happens to be other decaying material for them to feed on for another generation.\n\nSo, best case scenario: a few days.  Worst case:  months.  Hopefully you'll get some nice hot, muggy weather and they'll be gone in no time.

with proper circualtion of air maybe like 5-10 hours and it depends on the size of the house. make sure u air it out u dont need to get high off the paint odors.

Bathing in rusty water:  May not hurt you, but who wants to. It may discolor your hair, though.\n\nAnimals drinking:  They drink all kinds of impure water, but I wouldn't give them rusty water if I didn't have to.\n\nCooking: I would get some bottled water before I cooked with it. Even if you boil it first, the iron from the rust could be harmful over a period of time because it will not boil out.\n\nSome helpful advice: Instead of asking a new question (which costs you -5 points each) on an ongoing subject just edit your original question and people will come back to add to their previous answers or additional new answers may be posted.

Yes.  You can form a supersaturated solution with salt and boiling hot water in a glass jar.  Tie a pencil to one end of a string and a paperclip to the other.  Allow the pencil to rest on the top of the jar so the paperclip can hang in the solution, almost touching the bottom of the jar.  Allow the jar to sit undisturbed and you'll see crystals forming within 24 hours.

Water fleas are important in examining water quality because they are ubiquitous organisms that are very sensitive to environmental stress, they are easy to culture and feed, and you do not need an IACUC permit to possess them.
