The Hornets opened the scoring on 18 minutes when Sparks’ deflected 25-yard strike flew into the top corner.
And Horsham doubled their advantage on 34 minutes. A great pass from Lee Harding found Ajakaiye, who rifled home at the second attempt.
The Bears nearly grabbed a late consolation goal, but Hornets keeper Lee Carey did well to push a goalbound shot up on to the crossbar before claiming the ball.
