The problem before was that it was impossible to not "contain" it if it goes right (at least with the previous sterilisation approaches), because a certain area got rid of mosquitoes too quickly, therefore not spreading that infertility wide enough, and then they just moved in again from other areas.
To be fair there's some truth to it, they're just an asshole.
Some ceramic dishes tend to accumulate some water over time and then that water gets hot, while the food stays cold.
That shouldn't be a problem in new dishes or ones made out of glass or plastic
