Bayvarol is too expensive and do not know why it didn't worked for me (talking of 7 years ago), how ever Verostop http://www.centrovet.com/index.php?option=com_content&view=article&id=325:verostop&catid=100:antiparasitarios&Itemid=133 that I used past fall/autumn did work perfect. I guess it is the strip (plastic in bayvarol and wood in verostop) what makes the difference. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
