mmk...I found some info....some of it is pretty off the wall, but I'm sure you're willing to try anything at this point.
Hard boil eggs - take the yolk out and mash with boric acid. Put in a little alum. foil bowl behind refrigerators and under sinks...
sprinkle pure boric acid behind the stove and under sinks - your cats probably won't be able to get back there (and if they do....start entering them in some shows). I read that if you can see the boric acid, it is too much. Apparently the roaches will avoid it if they can see it - who knows.
make a mixture of powdered sugar and baking soda - put in alum. foil cups and put them in your cupboards. The sweetness will attract the bugs and the baking soda makes them explode (take pictures).
Move your refrigerator out and sprinkle some boric acid down. The kitties won't be able to get to it and neither will DS. Have bf move the fridge for you.
Apparently a good way to get the boric acid down without it being too much is to put it in a spray bottle and you will get a fine mist.
A roach's favorite food is not garbage...it is glue (from boxes, bags, etc.)....put everything with a glue seal on it (everything basically) in a plastic bag.
Step on every roach egg sack you find and then clean it up....when a female dies, she expels an egg sack - which will give you quite a few more roaches.
Diatomaceous earth is apparently great for roaches - killing them that is - you should be able to find it at garden centers and it is non-toxic for your family and kitties.
lastly - get a few geckos....I'm not sure how long they will last - but the kitties should enjoy them for awhile before they kill them

Geckos like to eat roaches....and kitties like to eat geckos.
