I am staying with my sick cancer sick mom on Pecos Road and Val Vista in Gilbert Arizona. So far not a one, but we don't have a black lite. And it's an apartment, and mom used to have them spray monthly. We have a big crack in the outside door they could easily get in....but I doubt they would go upstairs to access us. Still it seems they can be here too. Management says they have only seen one in the business center at this complex. One too Many for me !!
