Well, the exterminator came and found
no evidence of any critters!! He said to wait and see if I heard them again.
So for a week after his visit all was silent.
On Pascha morning at the break of dawn, 5:30 A.M. exactly, I was awakened after only one and a half hours of sleep (got home from the after Liturgy meal at 3:30 A.M. and didn't fall asleep until 4 A.M.) by my critter demons who decided to start making ALOT of noise in the wall right next to my bed!!
I announced outloud to them that 'Christ is Risen', to which they immediately fell silent for a few minutes, only to start up a ruckus again for fifteen to twenty minutes, and then they disappeared.
It seems that my critter demons like the Protestant tradition of celebrating Easter at dawn over the Orthodox tradition of celebrating after Midnight!!
Anyway, I haven't heard a ruckus since, though I did hear some faint noise elsewhere (though not that type of noise) last night, so I am going to call the exterminator back and have him go to his Plan B, which was to apply a deterrent around the base parameter of the house which sticks to any critters upon entering, and because they don't like it, after a couple of times, the smart, disgusting rats and/or mice put two and two together that they stuff comes on them from the house, and supposedly, that keeps them from visiting again.
Since it doesn't cost too much, and since my nerves get frayed, and I am thorougly disgusted and scared by the idea of rodents, I am going to call him on Monday...and hope that it will work--if they do indeed exist!!!

Ofcourse it works out that my husband is always away on business when all this excitement transpires!

Thanks for asking,
Alice
