Bacillus thuringiensis-How focused? How selective?
I don't like the idea of using insecticides, pesticides, herbicides ..chemicals of any type, even chemical fertilizers but, because it is supposedly natural, generally benign, etc., I'm considering trying Bacillus thuringiensis to control mosquitoes and certain other BTs to help control other pests.
Are these really as focused to one specific target as they claim?
Will Bacillus thuringiensis, for example, kill Mosquitoes, nothing but Mosquitoes and have no effect on Spiders, Mantises, lacewings, Ladybugs, wasps or other desirable predators?
Willow beetles, for example, are supposedly susceptible to Bacillus thuringiensis but might lady beetles be collateral damage?
Probably my greatest concern is that I have a huge, healthy worm population I do not want to harm.
Is it really a case of "Eliminate the Pest, Safe for the rest"?(Copyright 2011. BT manufacturers, contact me for use, permission and where to send the checks ;) )
Has anyone seen a comprehensive list of specifically what is effected by each BT strain?
