Q.How Do Agave Weevils Move From One Plant To Another?
I have quite a number of agave plants and some are keeling over due to the dreaded weevil I have sprayed them all with imidacloprid and soaked the soil at the base which I hope will stop the infections. I cannot establish how the weevils move about, do they fly or just walk from one plant to another as I have infected plants over quite a wide area? So do I have to water a large area of soil around the plant to catch them on the move? If they fly I have no chance.

Being a beetle... They will move from plant to plant by any means necessary! This means that they will crawl or fly from plant to plant, and constant mitigation will be necessary. Triazanon will be the appropriate chemical control, however.
