It sounds like your dogs are bored and looking for something to do. Our lab gets this way sometimes and eats my rose bushes occasionally, and the best remedy is exercise. If we take her for a walk once around the block, it helps to relieve anxiety and make her tired which makes for a well-behaved pooch. Give it a try to see if it helps. Since it's a short walk, I insist that my dog walks the entire time besides potty stops. I don't let her stop to sniff for fun b'c I need to get her energy out, and I don't have all day to wait on her sniffing stops.
