Wasps made it eight competitive wins from eight at Adams Park this season after seeing off Sale 25-18, who - despite a battling display which earned them a bonus point - remain well adrift at the bottom of the Aviva Premiership standings.
Sale, who suffered a record Heineken Cup defeat in losing 62-0 at Toulon last weekend, outscored Wasps two tries to one through efforts from Richie Vernon and Johnny Leota as Rob Miller kicked two penalties and a conversion.
However, it was Wasps who took the spoils thanks to a try from T Rhys Thomas, 14 points from the boot of Stephen Jones and further penalties from Elliot Daly and Nicky Robinson.
