Tobacco vs. sevin
How should I get rid of nest parasites? When a landlord discovers parasites in a martin nest, a complete nest replacement is the safest way to get rid of the parasites. Instructions for doing nest replacements may be found in Update issue 9(2), “How and Why to Do Nest Replacements for Purple Martins”: http://www.purplemartin.org/update/92nestrep.html Some landlords put the pesticide Sevin in their martin nests, but this practice conflicts with the recommendations of the manufacturer of this pesticide, and is not recommended by the PMCA.
