I believe that crabgrass is an annual; ie, it does not automatically return next year. this year's high heat and dry summer caused a lot of growth.

I believe the best solution is to over-seed your lawn this fall so that the good grass gets a start. Then, next spring, use a pre-emergent weed 'n feed. ( I prefer Scotts). That will prevent next years' crab grass crop from sprouting your yard. Use the good grass to crowd out whatever comes up.
