I wish I could say the birds and lizards are helping keep them down in my yard but truth is you can't go outside for longer than 10 minutes without getting attacked. For me to tend my plants along the woods edge I have to put on some off spray or they will swarm in clouds to attack. We have the Asian tiger mosquitoes here and they bite 24/7 not just in the evening. They bite through shirts and jeans so trying to where long selves and jeans don't help. I'm so surprised but grateful more Zika cases haven't been reported in my area. We only have 1 travel-related Zika virus confirmed so far in York county SC.
