So sorry to hear this. I hope some manage to survive 
I know there was research going on into the possibility that insecticides brought into the nest on pet and animal fur might play a part
I sent in some finished nests a couple of years ago for analysis but I haven't heard any results as yet.
There are so many factors that have to be just right it's incredible.
