These are terrestrial Isopods known as Woodlice or Sow Bugs, and they are benign.  They are generally found in moist environments where they feed on decaying organic matter.  Though it is a North American identification site, the information on BugGuide is relevant.  According to BugGuide the habitat is “wherever cool, dark, moist places are available to shelter woodlice from dryness and heat during the day” and their food includes “Plant material, usually dead. If live plants are soft and moist enough on the outside, they will eat them and sometimes do damage.”  Is your operating theater on the ground floor or below ground in a basement?  They are likely entering through cracks and spaces in the walls, so sealing off the operating theater from the outside environment should remedy the matter.

Hello sir..
Our operation theatre is located in 3rd floor above the ground..
And we noticed these bugs in OT after a rainy day…
Thank you for your valuable time..
I will revert back to you , when necessary…

Dear Albert,
We always love getting submissions from Alaska.  This is a Woodlouse or Sowbug, a terrestrial Isopod in the suborder Oniscidea.  According to BugGuide, they are found:  “wherever cool, dark, moist places are available to shelter woodlice from dryness and heat during the day” and they feed upon “Plant material, usually dead. If live plants are soft and moist enough on the outside, they will eat them and sometimes do damage.”

Subject: about 20 of them apear dead each morning.

Lawn Shrimp

Dear Fernando,
These are terrestrial Amphipods commonly called Lawn Shrimp or Househoppers, and they are an invasive species introduced from Australia.  According to BugGuide:  “
These are rarely seen except when flooding or lack of moisture forces them to abandon their home in the soil in search for suitable conditions. At such times they often end up dieing on pavement or in homes and become a nuisance. Once they start appearing, there’s not much that can be done except to sweep them up- pesticides are pointless, bcause by then they’re already dying or dead.  The best solution is to keep the numbers down the rest of the year by keeping the soil from staying too moist- in California, especially, they’re a sign of overwatering. Physical barriers like weather-stripping can also help to keep them out of homes, but their bodies are flat and narrow, allowing them to slip through surprisingly narrow cracks.  Non-native; introduced probably from Australia along with blue-gum eucalyptus trees in the 1800s. First recorded in San Francisco, CA in 1967.

Daniel, thank you very much for the information , indeed they look like small shrimp!!!!
I greatly appreciate your time.

Saw these mating….what ever they are…. along the inlet area of Beaufort, S.C.
I have looked in all my bug books and I can’t find anything like them. Can you tell me what they are?

Mating Warf Roaches

Dear Janet,
Your image is awesome.  Though they are sometimes called Warf Roaches, these are actually Marine Isopods, a type of Crustacean related to the terrestrial Wood Louse.  We are confident that we have correctly identified your mating Warf Roaches as
Ligia exotica thanks to BugGuide where the range is listed as:  “Atlantic coast NJ south to Florida.”

Every summer I get these in my room. I have a wall a.c. unit. I always think this is the way they get in but then I find them coming out from under my bed. I live in Florida. I thought I got rid of them but I guess it was the cooler months. I need help.

Dear Stephanie,
This is a Woodlouse and they like damp conditions.

After a more general cleaning of my home, the next day I noticed this bug walking on the wall. It might have come out of the wooden beams(I live in the last floor, roof floor kind of an attic). It seemed to be intelligent because it moved only when I was gone. I took a picture while it was there. To take in account, our house has damp problems, but apart from that we try to keep it as clean and as dry as possible. There is not much light in the room in general. This bug was around 1cm long, it was the last days of April when I saw it.
Thank you so much for the great work that you do, I will be looking forward on an answer to hopefully receive an answer for what kind of bug this might be!

Dear Katrina,
This is a common Woodlouse, a terrestrial crustacean often found in gardens.  Woodlice prefer dark, damp conditions.
