I would consult a homeopathic veterinarian http://theavh.org/
Many of them do phone consults, so distance is not an issue. http://www.vitalanimal.com
Check the blogs for information that may be helpful.

PS: You may want to rethink the pesticides….talk to your vet, however, a traditional vet will tell you one thing, but a homeopathic vet may advise you differently.
