Bees’ current loss of form is now becoming a major cause for concern.
Having bossed most of the first half at third placed Chester, they capitulated after the break and surrendered a 15-3 advantage into another defeat.
The result leaves Bees third from bottom with dismayed Director of Rugby Eugene Martin describing Bees’ second half display as unacceptable.
Martin said: “The scrummage was great and we looked to have taken a huge step forward there.
“But the line out was a disaster and we kicked too much possession away aimlessly and that came back to hurt us. The most frustrating thing was that we’d given ourselves a really good chance but the second half display was unacceptable.
Bees began brightly enough, winger Dai Evans racing over for a 12th minute try which fly half Adam Canning converted and then added a penalty.
Chester fly half Will Goodwin clawed three points back with a penalty but when left wing Aquile Smith scorched over for a second try, the game appeared to be heading Bees’ way.
Chester responded with a try on the stroke of half time through second row Ross White which Goodwin converted reducing Bees’ lead to 15-10.
But White’s try did more damage because it gave Chester the impetus to press forward.
Further tries from No.8 David Ford and fly half Goodwin, who also added a penalty put Chester 23-15 in front.
Although Bees gave themselves a glimmer of getting back into the game with another Canning penalty, it wasn’t enough and Chester put the issue beyond doubt with six minutes still remaining when replacement winger Peter Reef raced over for a try while Goodwin kicked the extras.
