The visitors started the better and were ahead inside five minutes as Tyrone Barnett poked over Loach after the Bees failed to clear their lines.
However, as the half grew on Peter Beadle’s side started to show some positive signs and were level seven minutes before the break as Wes Fonguck’s deflected strike went past the keeper.
JJ Hooper almost completed a dramatic turn around as his curling effort was well saved as half time approached.
The second half was a different story altogether, as Eastleigh were ruthless in the extreme and started the half with two quickfire goals from Wynter and House respectively.
The Spitfires showed more confidence throughout the second half and added a fourth when Miley beat the offside trap to poke home under Loach.
It was soon five for the Spitfires as Bell-Baggie finished off a good Eastleigh move to add gloss to the commanding scoreline.
The Bees will need to regroup quickly as they make the short trip to Dagenham and Redbridge on Tuesday night.
The boss was quick to apologise to Bees fans for the disappointing opening day defeat and has demanded his players immediately show what they are about on Tuesday evening.
