In my pool conversions. One in particular has a huge range of different sizes. That is probably mostly a difference in ages but there may be different species as well. The bottom of the pool is probably in the neighborhood of 20 x 40 and there are probably more than one larvae per square foot plus those hanging on the walls so I guess that there are probably close to a thousand which is amazing zika protection. And I have multiple pool conversions! Don’t you wish you were contributing to a non-toxic mosquito defense shield. :-) Bob 310 429 8477 www.PuraVidaAquatic.com
