how to count roaches?

[Rizzolo]

i am curious what methods people use to count large quantities of roaches. i am dealing with B lateralis and B dubia.

it seems to me that with specimens that are all about the same size e.g. all adult, or all nymph, then you would weigh a few and just extrapolate.

however, with mixed sizes, it seems more complicated. i am getting rid of my surpluses to keep my colony sizes manageable, and want to make sure i am giving a fair count.

any suggestions are very welcome.

Depending on the number is question, depends on my method of counting.

If it's a request for a few hundred or less, I count them, then throw in a 10-12% overcount.

If more, I count about 50-100 out and weight them. Then using this method, I approximate the amount they want.

well i dont really care about lateralis i just count as many as i can as they are running from one tub to the next (im a fast counter)
but the dubia i do by hand as well as most other roaches
small roaches get guessed apon since no one really cares they just know they get what they paid for from me lol




thanx froggy
