Best solution for controlling 418MHZ equipment

I have a mosquito misting system that has a remote that operates at 418MHZ (three different buttons for various operations). I’m wondering if anyone has come across a transceiver like the RFXCOM 433 that operates at 418 for equipment like this? Alternately, maybe there is something that can intercept the 418 signals and convert them to 433? Any ideas would be appreciated.
