Ahmed did a great job assessing the trouble spots. We have an old house, hence several vulnerable potential points of entry. He definitely has great experience as he pinpointed several spots from outside first. He didn't try to rush anything - did his walk-through to locate best spots for the mouse poison and steel wool where appropriate. Explained everything very clearly - no sense of being rushed (I've experienced the opposite in the past where others might give you the sense that they have to leave as soon as possible because they have more important things to take care of).
On the first go-around, mission success in terms of limiting the house outside of the house... That being said, there were still some droppings in the garage after a couple of months. Ahmed stopped by again, and now that we know it's from the garage, he spent a bit more time assessing the walls. Turns out that there was a hole (not at eye level) that was still open - he's plugged that one as well, and now comes the waiting game. Hope this add-on resolves it once and for all. Thanks again for being so polite, yet direct, honest and friendly Ahmed. Cheers!
