After all the rain these last few months I am beginning to feel like I have opened up a mosquito hotel in my backyard!  Not only does the pond have "No Vacancy" they are starting to camp out in pooling water and splitting the rent with the sparrows at the birdbath.  In order to prevent the population from increasing further I have turned to Bt pellets (Bacillus thuringiensis), a non-toxic control that is safe for pets & wildlife.  I also learned through my research that running water scares them off, so I have upgraded the pond to contain a waterfall.  2 bonuses in one!
