Rose bushes roots/ useful?

I do not know what kind of roses were surrounding my entire yard but when I purchased the home I tried to remove them. Useless. Can I use them to graft fruit? Berries? Anything but roses?

Wasp identification

I was stung by a wasp from the hive shown in the attached photo, and had an allergic reaction. Therefore I am keen to identify the species. The photo is not very good because I was afraid to approach too closely, but hopefully there is sufficient detail for this purpose.

Bumblebees in house in winter

I have found 4 large bumblebees in my house in the last week. It is mid winter here in the Niagara Region and -20 C outside. They are sluggish and I believe coming out of my Xmas cactus that spend the summer outside in my gardens. Would they nest in 10 inch plant pots and be waking up now? I have been moving cactus in and out during seasons for 30 years without this happening.

Bugs outside my house

I previously ask this question but sadly the pictures I had taken weren't really good, so a few weeks ago I came home and found this insects all over the frames outside the house , they jumped when we sprayed them and after that day we hadn't see them, until today they came back, again , it seems they come out when it rains, and is soo many of them, any idea of what could this be? Thank you so much your help.
