If ya can afford it, get the ortho home defense max and use as directed - not the one for bed bug, flea and tick but if ya have all of these critters ya will have to use chems in stages.
Wouldn't suggest it if I had no experience with it. They will eventually come back cause the structure is infested but will minimize the bugs for sure. This will not work against bed bugs jfyi in the case that this is also an issue... let me know if it is.
OTC Bed bombs are known to be ineffective as they run and hide in places that the fog wont reach and after all is said and done it can make matters worse.
Keep it posted and add anything else ya may think of and I will try my damnedest to help ya with this.
