Hahaha ...lol ...sorry .... they had already started multiplying , when you were busy killing those 99.9 % ones :)

it adapted to your system and transformed and became one with you. To kill it you be doing yourself in.

You might not want to do that. You'll need them. I had a girlfriend who did a successful job at killing off a good portion of the beneficial germs. She developed fungal patches around her body that the good germs helped to fend off.

they re hiding within you.

Don't you mean 0.1%? Anyway, assuming you're serious about that I would advise you against using antibacterial... well, anything (unless you're performing a surgery or something). First of all, many of the bacteria that you are killing off are actually beneficial. Second of all, that 0.1% strain that you didn't kill off will multiply (very quickly) and the subsequent strains will be resistant to whatever anti-bacterial agent you're using. Third of all, frequent use of antibacterial products has been shown to negatively impact the immune system because you're not exposed to the bacteria that your body fights on a day to day basis, so it's weaker & slower when it actually does encounter something it needs to get rid of. I think anti-bacterial products are going to create a super-strain of bacteria that will result in zombies =P

The .01% of the germs would have developed immunity to whatever anti-bacterials you have been using and will multiply in a mutated drug resistant form and you will find new generation anti-bacterials to get rid of them all over again. If you good really achive an elimination of 99.9% of all desease causing germs - that in itself is a great achievement. Normally bacteria start developing immunity to the drugs you use long before you get to the 60% mark.

You can't... by the time you were busy killing the 99.9%, they gained more resistance. Get a better killer now...

Hiding in warm and dark places.

killing 99.99 & bacteria is the most important 0.01% of bacteria is not important thing you immune system could handle it Also that's not necessary you killed exactly killed 99.9% of bacteria they just but that because no one can be sure how much you killed of bacteria ! Don't bother yourself with that !

The built themselves a steel and concrete bunker, and installed an oxygen cracking system, and grow their food hydroponically. They're secretly building a doomsday device to re gain their lost terrirory.

You do not want to kill all your germs as some of them are beneficial. Its quite easy to be too clean, as counterintuitive as that sounds, and leave oneself open to secondary infections that you ordinarily would fend off but end up getting because the good germs and bacteria have been removed.

1. Killing 99.9% of microbes might be ok for countertops and floors, but may not be the best idea for some things, such as your skin. 2. You'll never kill 100% of the microbes in any given spot. There are always resistant ones that you aren't going to be able to kill left. For example, you wouldn't be able to kill Deinococcus radiodurans, aptly named "Conan the Bacterium," with much anything. Throw whatever chemicals you want on on the countertops, you could even irradiate them with a GAMMA RAY BURST (which would kill all of us in the process) and they would sit there going about their business. You see, Conan will happily live on radioactive uranium, and eat bleach, rocks, organics, and a number of other things if it has too. The first time they found "Deinococcus radiodurans" it was in a can of spoiled meat that had been irradiated with radioactive cobalt, which was thought to emit enough ionizing radiation to kill any living microbe... or so we thought. So don't stress out over it. There are always going to be survivors in any attempt to disinfect. The ironic thing is the more we try to keep our homes and bodies clean with disinfectants or sanitizers, the more we give resistant microbes a chance of developing and thriving. This is why you should ALWAYS finish that round of antibiotics you get from the doctor when you are sick. It's usually a cocktail of 3+ antibiotics that shotgun whatever bacteria you have. So even if it has or develops resistance to one, the other two will kill it. Just take the whole course of them so there are no potentially resistant bacteria left(penicillin and many other antibiotics no longer work due to resistances, dis is serious bizzness).
