With 12 bins and each one having had about 500 beetles in them at some point for a week or more and estimating that at least 250 beetles are girls and laid eggs every day during that time then I am saying I probably have around 50,000 mealies growing up in each of the bins and with that being 12 bins then.........uh.....uhm......er .........I plead mealie math!
Or hubby. Or other relations who might not understand the importance of mealie-sorting!
