Barnet remain one point from safety after slipping to a 2-1 defeat against away-day specialists Swindon.
Ellis Iandolo and Matt Preston scored either side of John Akinde's header with all three goals coming in the first half.
In the 17th minute, Iandolo put the visitors ahead as he caught Craig Ross off his line and scored with a 35-yard free-kick from the right wing.
The lead didn't last long though as Akinde headed in from Jamal Campbell-Ryce's cross to level in the 20th minute.
The Robins nearly restored their lead moments after conceding as Luke Norris forced Ross into a low save.
With the last kick of the first half, Preston's close-range finish from Iandolo's cross restored the lead for David Flitcroft's side.
In the second half, Jack Taylor's effort was smothered by Reice Charles-Cook.
The Bees came close to equalising when Akinde laid the ball off to Mauro Vilhete who had a shot deflected and the ball looped just over the crossbar.
