Stephen Kerr (Stirling) said the words “traitor” and “lies” were sprayed on to the exterior walls following the heated exchanges which saw SNP MPs storming out in solidarity with their leader Ian Blackford.
He said the “ramped up rhetoric” during Wednesday’s PMQs triggered a renewed stream of abuse.
Raising a point of order, he said several SNP MPs behaved in a “threatening and overly aggressive manner” by “shouting and gesturing in the direction of myself and other Scottish Conservative colleagues” when they walked out of the chamber.
He continued: “Since our election last year, Scottish Conservative Members of Parliament have been targeted by online trolls and subject to a constant stream of threats and abuse, including death threats.
“Several instances have been reported to the police and there have been court appearances, our constituency offices have been targeted for aggressive nationalist demonstrations and our staff subject to vile threats and intimidation.
“The sad reality is that the ramped up rhetoric of last Wednesday inevitably triggers a renewed stream of such abuse, and my constituency office in Borestone Crescent, Stirling, which has been vandalised several times in my first year as a Member of Parliament, was again attacked overnight on Wednesday.
“An unknown person or persons spray painted the words “traitor” and “lies” on the exterior walls of my office.
“This latest incident has also been reported to Police Scotland.”
He asked what the Speaker John Bercow could do to “advise SNP members to practise a modicum of self-restraint in respect of their language and behaviour”.
Mr Bercow urged MPs on both sides of the House to “recognise the impact of their actions”.
