As embarrassing as this is, I thought I should share to keep others from having the same thing happen to them. About 3 weeks ago, we purchased a used refrigerator from Craigslist and brought it home. We pulled it out about a week after we first brought it home to install the water line and realized that there were cockroaches in it! By that point they had already made it into the house itself, so we have been battling them ever since. I think that the tide has finally turned in our favor. I have not seen one in almost 5 days and I had been seeing them, even in the daytime. We put out Magnum Quantum FC gel baits and Gentrol Growth regulator and it seems to be doing the trick. The moral of the story is always be aware of what you are bringing into the house.
