I emptied the water out of a large bowl I had left outside the other day, but since it rained again yesterday I went to empty it again today and found about ten of these baby shrimp in the bowl. I live about 5 miles from Mobile Bay, but I still thought that was kind of weird… then I found your page and concluded they might be lawn shrimp. The antennae fell off before I took the picture.

Lawn Shrimp

Hi Ray,
You are correct that this is a terrestrial amphipod known as a Lawn Shrimp.  They are also known as House Hoppers because they sometimes enter homes in large numbers after a rain.  Lawn Shrimp are native to Australia, but they have been introduced to North America, and most of our reports come from California.  We have also gotten reports from Florida, but we believe your account from Alabama is a first for us.  Lawn Shrimp can proliferate in great numbers in gardens, but they are generally not noticed until it rains and they enter homes where they quickly die.

    Found them at the bottom of cat’s water bowl last couple of days after several days oh heavy rain, soil saturation and flooding . So they guess they’ve hopped over to Texas, as well. Lakefront at beautiful Lake Conroe.

    confirmed sighting in Houston, Tx. Freaked out one morning after all of our rain recently. swept up hundreds by the front door (inside). walked through them in the dark barefoot, Super!…. good news is that they do die indoors quickly.

    In the last couple of years I have had hundreds of these lawn shrimp come in my house. I just the other day found out what they were. I live in Pascagoula Ms. By spraying around patio door seems to have helped to keep them out.

    My entire driveway was cover with this bug and they were all dead last year summer of 2018. Today April of 2019 they are back dead all over my driveway only in the backyard. I have been living at this home for over 30 years and this is the first time I have seen or heard of this bug. What can I do to get rid and is it harm to animals?

    Fort Worth, TX My granddaughter discovered one of these, 1 1/2 inches long, not including antennae, in our yard, not long after a heavy rain. How are they migrating? We have one damp area where house runoff keeps the red clay watered and sidewalks prevent quick drainage but the rest of our property is a 1 acre dry field.

    They’re in our yard and now in our pool on the coast of NC. Not sure how to get them/keep them out of our pool.
