Strength Level: Superhuman strength, able to lift approx. 6 tons

Known Powers: May posesses powers inherited from her father, including the proportionate strength, speed, and agility of a spider. While unable to lift 10 tons like her dad, she is more agile than Peter. May also has super equilibrium; the ability to cause parts of her body to stick with great tenacity to most surfaces; and a subconscious premonitional "danger" sense known as her "spider-sense". Unlike Spider-Man, May can reverse her ability to cling to walls and actually repel from them.

It doesnt sound like Spider-Girl (May) can shoot webs.
