It is very difficult to get an idea of what it is without (a) your
approximate location and (b) more details - like what size, etc.

If you are in eastern Australia then it *could* be a red-and-blue
beetle (also called a football beetle), which can reach huge
populations. This is actually a beneficial beetle - they eat aphids
and caterpillar eggs. However, your description is vague and could
apply to any number of little creatures, including sucking bugs (which
can look like beetles).

If you are in a city then you could capture some and take them into
you nearest university of dept. of Ag. office to get identified.

Hope this helps,
Tish

I have a very small insect/beetle invading my garden, and having a lovel
time.
It is also coming inside the house, and is in the dogs coats.
It is small, and has vivid red & green band stripes across its body.
Can anyone help me to identify this pest (to say the least), and help me to
eradicate it.
