Question: if we are not experiencing cicadas, is it ok to take the nets off of our trees?

Question:
I live in central Indiana and have had no cicadas yet. Are they still emerging or is it safe to uncover my tender trees?

Answer:
If you haven't seen or heard any 17-year cicadas near your trees yet, there probably won't be any emerging there this year. You should be safe to take off the netting now, but I'd still suggest learning the signs of cicada egg laying damage and keeping an eye on any trees you're worried about. The damage typically looks like a row of small holes in the bark connected by cracks (exp. periodical cicada (Magicicada septendecim) but it can vary depending on the species of plant. If you see signs of egg laying damage, you can put the netting back on to protect your trees from any additional injury.
