Dwarf Fountain Grass Grub Damage
Grubs in Texas only tend to harm certain plants. Mediterranean Fan Palms and some types of grass like Mexican Feather Grass or Dwarf Fountain Grass can really get major root damage. The grass in the picture is a Dwarf Fountain Grass where all the roots were totally shaved off by the grubs. I just reached down to inspect the grass and it just came right up. If you look closely you can see about four grubs that were making a meal out of the grass’s roots. The insect in the other picture is a Masked Chafer and is the primary source of grubs.
We operate under Texas Department of Agriculture Applicators License #611373. To maintain the license we are required to acquire ongoing educational credits every year by taking approves courses. Through over a decade of experience and training we have found that applications in May & July can help keep grubs numbers to a minimum. You will never be rid of all grubs but you can keep the population in check enough to prevent plant damage. If the grub population stays low it will usually keep the armadillos from coming into the landscape.
The only way to really rid the landscape of almost all grubs would be to treat the landscape every month from late March thru the fall. We really try not to upsell excessive applications so we simply target the two most effective times of the years to do the most good with the least amount of applications. If grub issues flare up during the other months which can happen on occasion we simply treat as needed.
