They say they are going to be pro-active and adopt a high visibility patrolling strategy with particular attention paid to locations where problems had arisen in the past.
Chief Inspector Jane Humphries said: "Last year, across F District (which includes Fermanagh) we seized almost 5,000 fireworks in the weeks up to Hallowe'en and on the night itself. Already this year we have made a number of seizures."
She encouraged local people to report incidents and concerns over the illegal trade in fireworks to police.
"We have been visiting schools, shops and licensed firework retailers to remind them of the legislation and to encourage them to put their communities first," she said
"When we detect offences, we will look at our range of disposals, and that includes prosecution. When we seize fireworks from young people, we will write to their parents advising them of the situation," she added.
"Hallowe'en is supposed to be a fun occasion and not an excuse for lawlessness. Please consider residents who are infirm, elderly and vulnerable and behave in a manner which will not leave them feeling intimidated in their own homes and afraid to go out," said Chief Inspector Humphries.
"Hallowe'en is becoming one of the busiest times of the year for the police service. This year we are making it clear that anyone caught breaking the law will be dealt with robustly. It is possible to celebrate safely, but that does not include letting off bangers or throwing fireworks at individuals or vehicles," she stated.
