Deer move freely through our landscape. We both have that same "What are you doing in my yard?" expression when we see each other.
If you face a similar situation, look for the NO DEER symbol to minimize frustration.
Ladybugs (eggs to larvae to adults) thrive in healthy gardens. You can buy them and release them, but it's the plants that naturally induce, sustain, and keep them in the gardens. Several years ago, I stopped spraying pesticides in and around the gardens. It struck me as being slightly psychotic to plant a landscape that attracts birds, bees, and beneficials into my landscape and then turn around and use chemicals that harm them.
