An agave snout weevil is about a half inch long black beetle that is the biggest enemy of many agave varieties. It pierces the agave’s core and then consumes the agave’s heart which will cause it to fall over and die. The beetle will burrow into the soil and hatch their eggs which turns into grub worms and consumes the heart of the cactus. How to detect when it is infected, the base will begin to turn yellow or dark brown at the bottom branches and will begin to droop. Another way to detect infection is to grab the heart and shake it and if its very loose it’s probably infected and no longer savable. It is strongly recommended that all agaves need to be treated whether they are infected or not just to prevent the agave snout weevil from attacking it because once they infest agaves they are extremely difficult to get rid of.
