Mr Vijayan also taunted the BJP's Jan Raksha Yatra, saying the results of the party's month-long campaign appeared to be negligible as the people of the state had spoken against it in one voice.
He accused the BJP and its ideological mentor, the Rashtriya Swayamsevak Sangh (RSS) of carrying out a "malicious campaign" to tarnish the image of the state and damage its tourism industry.
"A 'boycott Kerala' campaign is being run with the call to bring tourism in Kerala to its knees. People of other states are asked not to come to Kerala so as to bring our tourism industry to a standstill," Mr Vijayan claimed.
The Chief Minister said the BJP had even routed its yatra through the Vengara constituency but the victory of the Indian Union Muslim League had put paid to its efforts.
"Despite dirty tricks and attempts for communal polarisation, BJP has been relegated to the fourth position with a much-reduced vote share. This is a pointer and strong warning to the BJP that they can't mess with Kerala."
