One of our cats now living outside because he peed all over the house used to kill them. Play with them until they fell apart. The 3 cats still in here ignore them. I see them in the living room at night and there is no food here. They're in the kitchen at night so I know what you mean. RR used to take the trash out at night - I think the trash draws the ones in the kitchen but they can't get up the slick sides of the trashcan. I haven't seen one in the bathroom in months.
He's coming back to spray again this Tuesday. The fleas are almost gone. They're another pest here in FL and they're year round.
