The invention discloses a multifunctional garden street lamp comprising a solar street lamp body which mainly comprises a lamp post, a lamp holder frame, an LED lamp holder, a solar cell panel and a distribution box. Heat emitted by the LED lamp holder is transmitted to a medicine cylinder heat conduction seat via a lamp holder heat conduction seat and heat conduction copper pipes, and meanwhile internal temperature of the medicine cylinder is improved by using a medicine cylinder heat conduction seat, so that the effect of heating a mosquito repellent medicine is achieved, volatilization speed of the medicine is improved by heating, and thus mosquito repellent efficiency is improved; meanwhile, space between the medicine cylinder and the LED lamp holder is suffused with pesticides, so that mosquitos are killed, the killed mosquitos fall on a net and thus the killed mosquitos can be collected so as to be convenient for subsequent clean; and meanwhile, the heat conduction copper pipes play a role in supporting the medicine cylinder, and thus overswinging of the medicine cylinder caused by external air flows is avoided.
