Yes Kama is greatest enemy amongst the Six enemy’s (Shada Ripus).
More appropriate version of Lust is Kama or Deisre. Lust is sexual Desire while kama is generalized form of desire, Kama is most powerful amongst Shad ripus.
Arjuna asked a similar question to Krishna, following is the enquiry about the force which leads jiva to do sinful acts (as if forced to do it)
आर्जुन उवाच:
अथ केन प्रयुक्तोयम् पापम् चरति पुरुष: ।
अनिछ्न्नबपि वार्ष्णेय बलादिव नियोजित: ॥३.३६॥
Arjuna said: O descendant of Vrishni, by what is one impelled to sinful acts, even unwillingly, as if engaged by force? BG 3.36
And Krishna Answers it in next verse
शरि भगवान उवाच:
काम एष क्रोध एष रजोगुण समुद्भव।
महाशनो महापाप्मा विध्येन मिह वैरिणम् ॥३.३७॥
The Supreme Personality of Godhead said: It is lust only, Arjuna, which is born of contact with the material mode of passion and later transformed into wrath, and which is the all-devouring sinful enemy of this world. BG 3.37
Kama can be defeated in two ways
1) by Controlling Food habits (Easier)
Avoiding these food items will remove rajas (as much as possible)
कट्वम्ललवणात्युष्णतीक्ष्णरूक्षविदाहिनः।
आहारा राजसस्येष्टा दुःखशोकामयप्रदाः।।17.9।।
Foods that are too bitter, too sour, salty, hot, pungent, dry and burning are dear to those in the mode of passion. Such foods cause distress, misery and disease. BG 17.9
2) by Becoming Atmajnani
एवम् बुद्धे: परम्बुद्ध्वा संस्तभ्यात्मान आत्मना॥
जहि शत्रुम् माहाबाहो कामरुपम् दुरासदम् ॥३.४३॥
Thus knowing oneself to be transcendental to the material senses, mind and intelligence, O mighty-armed Arjuna, one should steady the mind by deliberate spiritual intelligence [Krishna consciousness] and thus—by spiritual strength—conquer this insatiable enemy known as lust. BG 3.43
