Dundalk says the club will issue lifetime bans to any fans caught with pyrotechnics at Oriel Park.
The club made clear their intentions in a statement released today.
They were prompted to address the issue after they received complaints following their clash with Shamrock Rovers.
‘After our recent home match against Shamrock Rovers, the club received numerous complaints about the behaviour of a small number of fans," the statement read.
"We have a message for this small number of individuals, who again showed disregard for the safety of other Dundalk fans by using flares during our recent away matches with Bohemians and St Patrick’s Athletic, with the potential to cause harm to innocent bystanders and people doing their jobs.
"To these individuals, who have also recklessly used fireworks and have no regard for the wellbeing of other Dundalk supporters – if you are caught with flares, fireworks, smoke bombs, or any pyrotechnics, we will issue them with lifetime bans from Oriel Park and will work with other clubs to ensure they don’t attend away matches either."
The club says they appreciate their supporters, but that issues had been raised by the FAI and RTÉ.
"We are not trying to stop you from enjoying matches, we need our fans more than ever and, let us reiterate, your support is greatly appreciated by all at the club, none more so than the players and staff.
"The FAI are not being unreasonable in their alarm of these actions and RTE are not being vindictive in reporting the club for concern for the staff, we are simply trying to protect all in attendance against the dangers of these items.
"The Health and Safety of all people attending our matches in Oriel Park is paramount to us and extra security measures will be in place for all remaining home matches this season."
