do cockroaches die when put in hot water?

Yes, hot (preferably boiling) water would indeed kill cockroaches, assuming you could keep them in the water for the several seconds it would take to kill them.\n\nCockroaches, like most insects, have a waxy coating or cuticle on their exoskeleton that aids them in regulating water loss from their bodies.  Because of this, most insects have at least some ability to swim, and cockroaches are no exception.\n\nAssuming you had a captive cockroach and a pot of boiling water, what would probably happen is you would drop the cockroach in the pot, and the cockroach would immediately swim for the edge of the pot, climb out and run away before the boiling water killed it.\n\nShould you be able to contain the cockroach and keep it from getting out, it would indeed die.\n\nWe often use boiling water to kill insects before identification, because the boiling water kills them very quickly, but without deforming or discolouring the insect.

cockroaches have exoskeletons

It depends on the insect. Some die off leaving eggs behind to hatch next season (like the Praying Mantis). I have heard some critters replace the water in their bodies with glycerin so they don't freeze during the cold months.

PLEASE READ!!!!!!!    An earlier reply to the lice problem by Thalia must be addressed.  (Please no offence Thalia)\n\n"DO NOT PUT COCKROACH SPRAY ON ANY PART OF YOUR BODY"\n\nCockroach spray is a pesticide and can be deadly.  It is not meant to go on humans or any other living creatures.  It is not meant to kill lice.  "Lice shampoo" is not good for our bodies, but may be used in small quantities for a short period of time.\n\nImagine the size of one louse and the amount of pesticide it would take to kill it.  Now picture the size of a cockroach and the lethal amount it would need.\n\nOH, MY GOSH!!!!!!  These girls are 13 years old!  Old enough to trust adults to know what we are talking about, and yet not mature enough to differentiate between right and something sooooo completely stupid.\n\nI'm sorry if I offended anyone, but I am absolutely MORTIFIED by this response.

According to the Article I listed below as the source, they can but cut in half, and you need to pour salt over them once this is done.\n\nThat's a bit gruesome, but fitting for a gruesome critter such as this Over sized Steroid pumped Cricket.\nApparently, a friend of mine told me that they have been found dead in her pool. this means they can be drowned.\n\nCatch it in a bottle, and drown it. Nothing else will work, as it's impervious to Insect spray, and it's exoskeleton is the same as a cockroach, meaning it can survive decapitated!\n\nYup, I say drown the bug.

Roaches might nibble and break the skin of an adult, but children are more susceptible to roach bites because their skin is softer and more tender.\n\nhttp://www.bio.umass.edu/biology/kunkel/cockroach_faq.html#Q7

the conclusion is that when you heat water it will boil.\nif you donot stop it will ecoporate

Well it depends if you microwave it then water the plant while it is still hot then yea it will kill the plant, the hot water will kill the plant you will scalded the rotes. But if you zap it then let it cool it would be just like any other cool water. As long as the plant is getting the other nurturance and light it needs it will have no affect at all.

The Cockroach. It survived the fist ice age.

only if you put the hot water in a colder system than what you put the cold water into

heterogeneous - Ever wonder why you need filters?  \n\nPipes go bad and you'll see that rust color.  Chlorine is added to disinfect the water.  What cannot be killed lives in your water, if you haven't filtered it yet.  It is not good to drink hot water because you'll have more particles dissolved in water such as lead, etc.

Depends on what the stress is...they will most likely try and swim away if they don't like it.  If they're trapped then they'll die if the stress becomes too intense.  Usually we use daphnia as experimental animals when studying effects on heart rates.

cockroach respires with the help of air tubes called trachae which is spread all over the body.Trachae opens to the exterior by means of 10 pairs of stigmata or spiracles which have valves.Air enters stigmata and is directly taken into the tissues where exchange of gases takes place.Blood has no role to play in respiration as in other animals and so respiration in cockroach(in insects in general) is said to be direct and more efficient than in any other animal.

Any bacteria or viruses die and hot temperatures and mot hot tubs are kept at 104 degrees.  I think that is pretty hot.

Lifespan of a Cockroach\n\n    * The female cockroach lays an egg case which contains about 14 eggs.\n    * She hides it in cracks and crevices, or may drop it in a briefcase, pocket or drawer.\n\n    * Nymphs come out in about 1-2 months.\n    * They molt 13 times for 6-12 months until they are an adult.\n    * They like the warm months of June, July and August. They can live up to 2 years.

not neccessarily. the heat will likely have a "ph effect" on the plants. if doesn't mater if the water is cold or hot, but it rather does matter if it has nutrients and sun.\n\nalso, too hot of a water will likely cook the roots, which means a dead plant! What does affect plant growth is the amount of sun it has.\n\nhumidity does have it affect on plants. humidity it basically the heat of the water in the air (people say its kinda sticky like)\n\nso overall answer, always use room temperature water for best results!
