Predictable...I still have bugs. I do subscribe to a couple of bed bug boards/forums that have self treating instructions that seem as effective as professionals. The good part is that the bed bug population is declining steadily, I haven't been bit since they sprayed, my apartment has never been cleaner, got rid of all the furniture that had bugs so now my apartment looks very zen. I do not think the bug guys are properly trained to eradicate a bed bug infestation. My allergic reaction to the bites is being treated medically. I still like to torture them as a form of bed bug therapy. I know a lot more about bed bugs than I ever wanted to know! They will all be gone from my home soon. I will take precautions so I can keep my home pest free from now on. But as for the rest of the world, bed bugs are going to be on the rise and it will happen quickly. These are the hardest bugs to get rid of. Now aren't you sorry you asked that question? Bahaha...
