Saw flies, they love mugo's.

Pine sawflies... I had some on the pine in Maine and I had fun dropping them off the lake dock into the water for the sunfish. I was almost sad when I ran out...

Ken,
Please o please tell me you're just getting ready for them. It seems I was just scrapping ice off my windshield.

For those Pine sawflies I take a 1# size empty coffee can with lid and rinse out the can. Pour about a quarter of an inch of gasoline in and drop them in.........that takes care of them. Oh, and put the lid on when your done!!!

I had these on my Mugo last year. I sprayed with a vinegar backing soda mixture used for black spot on roses. Don't know the mixture ratio right now - but easily found on the web. They dropped like flies - all were on the ground in minutes, dead by the next day. No damage to the mugo.

Yess!
Just caught the first ones! On time for once, not much damage yet.
The soap did it, first thing to my hand and I was in a hurry.

The poor denuded branches from last year are covered with tiny
stiff tassels of new growth, What a joy to behold!

I have ten Mugos and love them. Now I'm on patrol for the season.
There were some adults flying around, got some of them too.
The babies are hard to see, not all the same color either,
but as soon as I sprayed one lot, a nearby one raised its many heads
announcing its whereabouts, just water would have done that too.

I've noticed a few on my Thunbergii too. War has been declared.
