Beetles eating my herbs and other plants - Knowledgebase Question

Question by DinomLV

I have a problem that has come up with a new home that I purchased less than a year ago, where I planted a herb garden. I noticed that the most all of the herbs planted, basil, thyme, marjoram, oregano, etc. etc. (except for rosemary) were getting their leave eaten, but I could not find any caterpillars or other pests that would remain on the plants.

As the problem got worse, I found many dead small black beetles accumulating by my porch door. (See pics). So I went out at night and I found my plants covered with these beetles.

I eventually removed all of the herbs in hopes that these pests would subside, but then they attacked a small lime tree I planted and literally devoured it, leaving nothing but limbs.

I then began to notice a significant death rate to my grass, and in the areas of dead grass, in the soil I began noticing holes in the ground (See pics). So I’m assuming that these beetles are now eating the grass roots.

What can I do to get rid of these pests?

Thank you in advance for any assistance with this “plague”

It looks like a type of weevil (there are several different types of weevils and each has a favorite food source) but that's all I can offer.

Yes, they are root weevils. This article is from the Carson City paper:

I'm not sure how to get rid of the invasion you are having. Maybe call an exterminator.

Thank you for identifying the little buggers... I'll do some more research on the safest ways to get rid of them. Thanks again!
