The warm season variety of Bahia grass is common in yards and fields where humidity-resistant grass is needed. The main problem with Bahia grass is that insects enjoy it as much as humans do and make their homes and nests among the grass. If these eggs end up hatching, it could greatly harm your landscape. The key is to recognize insect eggs on the Bahia grass in order to get rid of them with pesticides before they hatch. Remember to put on gloves whenever you come into contact with grass you think is infested. Common insects that like to feed on grass include cutworms and sod webworms.
Examine your lawn and pinpoint any browning or bald spots, as this is usually an indication that insects are being destructive to your grass and root systems.
Look for dirt tunnels that rise from the ground, as this could indicate that insects are burrowing.
Run your hand slowly through the Bahia grass to pull it back and look for insect nesting, which will be identified by surrounding insects, damaged grass and sifted dirt.
Stick the top four or five inches of a shovel into the soil and push upward, as grubs may be present underneath the top inch. Doing this will help you see them.
Keep any insects you find in a plastic bag or canister in order to get them identified, via specialist or insect guide. This can also be a barometer for figuring out if your lawn is infested. For example, according to the University of Arizona, 12 grubs per a square foot requires a pesticide application.
