Today I found quite a few of these insects all over the floor in my
home. I have never seen them before, nor have I seen any of them
alive. I have posted an image of the insect at

Dear sfmarq

The reason why you 'might' not have seen any of these alive
is probably because they belong to the crustacean family
http://wri.sdstate.edu/album%209/pages/DSC01122c_png.htm
and 'should' live in the sea?

I couldn't find an exact match or name presuming this are land
creatures, but do you by any chance live by the sea, and they are
somehow introduced into your house?

Hi sfmarg,

Your insect visitors goes by many names:
Lawn Shrimp, Terrestrial Amphipods and its 
scientific name Crustacea: Amphipoda [1]

Some facts about where Lawn Shrimp pop up:

Terrestrial amphipods live on the surface (top 1/2 inch) of mulch and
moist ground. After rains, large numbers of amphipods can migrate into
garages or under the doors of houses. There they soon die. Amphipods
do not have a waxy layer on their exoskeleton as do insects. They lose
or gain moisture from their environment. Too much of a water loss
results in desiccation while too rapid a gain is also lethal. This is
why they migrate out of rain-soaked soil to drier areas where they
usually end up dying anyway. Most species are active at night.[1]

About Insect removal or management:
There is no chemical control recommended. Improving drainage will
reduce the likelihood you will see them again.[2]

Thank you very much for 5-Star rating! 

I appreciate it .:)

I think Lot is right. These certainly look like some sort of
crustacean critters from the sea. Attack of the Land Shrimps?
