See if you can identify the species and read up on the best methods for tackling the issue (see link below).In the meantime (before move in), I would get the over counter traps (little black ones) designed for roaches and put them under cabinets, appliances, etc (blue tape can hide them on the near walls of cabinets or back side of appliances).Then I would get the peanut butter type product designed for roaches that is in a syringe and inject a small dab into nooks, crannies, even inconspicuous places (like inside wall plates).Sprinkle some boric acid based powder (often with a sugar/flour or pheremones) under appliances, behind them, around the hot water heater, etc.

Vinegar and water solution 1:1 applied with an acid brush.

but I never had to really define that or use that as leverage to cure any problem, there was a drug usuage and prohibited items stored section, like no more than 50 rounds of any caliber amunition, gasolene or combustible fluids, acids...etc, not usually found or stored upon a residential premises. .

High End: Acid stained concrete in a color that isn't likely to clash.The tile you have right now will eventually come lose and or chip off.

They would drop acid and sit in the room with the lights out so as to pretend they were in outer space.

From what I’ve gathered thus far, in the end it basically boils down to the “passive” investment acid test (including intent to provide reciprocal loans as mentioned by Kaaren).Consider this scenario:Two completely unrelated investors share the common goal of funding individual investment opportunities in their respective (but separate) markets.

Acid is where it at.

Go to Home Depot/Lowes/hardware store and buy a container of boric acid.

She is probably completely acidic, which is fueling the fire.

It depends on the subfloor.If I have clean concrete (not too much adhesive, paint etc) I do stained concrete (acid first then marbleize with acrylic)If I have concrete which cannot be stained I tile.
