Bournemouth kept their late bid for a play-off place on course as Birmingham's misery on home turf continued as they claimed a 4-2 win.
The victory, which included a Lewis Grabban brace, lifted Bournemouth to 10th and only five points behind sixth-placed Reading.
Howe has seen his side win six of their last eight games to put themselves in contention but thinks the future will be decided by other teams.
"It is going to be difficult. If you look at the clubs above us their destiny is in their hands not ours," he said.
"They are the teams with experience but if we carry on the way we are playing and showing a fearless attitude then who knows what we are capable of achieving."
Bournemouth sealed their latest success and gained sweet revenge for a 2-0 home defeat at the hands of Birmingham with a purple patch in the first half with three rapid goals.
Matt Ritchie opened the account after 14 minutes and he was closely followed by Grabban who scored twice. He was on the mark in the 20th and converted a 27th minute penalty to take his goals tally to 19 this season.
Evergreen Ian Harte, who has an influential impact on the Bournemouth side, notched a fourth seven minutes into the second half with a clever, curling left footed shot into the roof of the net.
Birmingham's reply in a stirring second half comeback was two goals from the young on-loan striker Federico Macheda. He was first on the mark in the 57th minute and the second came after 72 minutes but it was to no avail as the midlands club were beaten by a confident Bournemouth.
Howe had every reason to be pleased with the outcome despite Birmingham's storming second half performance.
He added: "We are doing really well. We have had a very good month. On paper this was a tough month. We had a lot of away games and some long journeys for our supporters at crucial times.
"We had a great win at Doncaster and have built upon that victory. We have scored a lot of goals this month and as a result we look a more confident side.
"We scored four in midweek and five against Doncaster. There are good signs going forward. It was a really good first half for us.
"We looked a real threat and we played really well. Some of our football was pleasing on the eye.
Birmingham manager Lee Clark was also at a loss to explain what happened when Jordon Ibe left the pitch with a damaged boot.
Clark, who has not seen Birmingham win any of their last 15 home games, said: "We were the better team until the ridiculous first goal went in.
"We lost our shape and they picked us off. I couldn't believe what I was seeing with that goal. I was up in the stands sitting comfortably and I thought we had started really well.
"Then the lad leaves the pitch and it takes a long time to get him back on. By the time we do we are a goal down and I couldn't comprehend what I was seeing.
"I am not blaming the officials. We were poor defensively as it looked as we were not prepared to do what was right. We gave ourselves a mountain to climb.
"We scored twice at home and do not get a point. This tells me where we have to improve massively.
"The goals sent us tumbling and knocked us for six. We knew they would be a threat down the wings and it was so disappointing."
