Can someone ID this kind of bug?


I pulled an old plant out of a planter to use the dirt and plant something new. In the bottom of this dirt in planter I found 16 large caterpillar looking things. They are clear in color with brown heads and the size of a pencil fat and about 1 1/2" long. What are they.

I have never seen them before in any of my planters and I only use planters as I have to dirt area on my patio. They stay curled up and don't appear to try and climb out.

    Sounds like slugs, not caterpillars. Diatomaceous earth or sand or crushed seashells should cut them apart. They are attracted to shallow pans of stale beer, where they crawl in and drown.

    They are grub worms. They eat the roots of just about any plant except Marigolds. Hope this helps.

      Must be very careful they don’t spread. If you see Japanese beetles, they are the ones who turn in to grubs. There is an effective grub killer which I have used in my compost bin.

    Thanks so much I put them in a paper bag and in the dumpster for

    pick up today. I am even going to throw away the dirt in that planter

    for fear that there are more eggs or whatever they came from. First time ever, but glad they were in only that one pot. Think because it came from the 99cent store last summer, beautiful begonia, that because I didn't shake the dirt off of it when I brought it home and put it in that planter, that the eggs must have been on that plant. Sure hope I never see them again. Thanks loads for the answers

    And yes that plant was large and beautiful and lately becamse brown and dead flowers. When I pulled it out there were NO roots on it so all 16 of those things got nice and fat off of this one plant.

    Grubs, are the 'larvae' of various beetles -- the egg is laid on the soil, hatches, developes into the grub .... just feed them to the chickens or go fishing !

    Thanks so much. My uglies are in the dump as I put them in a paper bag and tied tight and in the trash. I also took that pot of soil

    and threw it in a empty lot next door. Hope I never see them again.

    Haven't seen any beetles here but think they were in the soil from the 99cent store plant.
