Cleaning and Stain Removal - Pine sap out of denim jeans?

Please help!!! I just had a baby and only have 3 pairs of jeans that fit. I attended my sons Cub Scout pack meeting and sat on a wooden bench beneath some trees (there was zero lighting in the area) and I then I find two portions of sap on the back side of my jeans.

Can anyone tell me what is best to remove it?

A solvent cleaner will remove sap--lighter fluid, mineral spirits, denatured alcohol, dry cleaning fluid. Some report results using WD-40. The trick will be to blot with white rag or paper towel from outside the middle to prevent spreading the sap. Then, pretreat affected areas with heavy-duty, liquid laundry detergent and wash. If solvent odor remains in clothing, hang to air dry until all odor has dissipated, as solvent fumes are flammable and volatile. Once there are no more fumes, wash again and toss in dryer.

I'd try the WD40 first, it's probably least likely to damage the jeans.
