Sorry. This winter will NOT reduce our fly, mozzie and tick populations. I have just confirmed this with Carol at IPMlabs.com A fingerlakes based pest management company. She recommends that the biting females be trapped before the next generation starts. I asked her to recommend some EFFECTIVE traps. Bite Free Starbar traps (the clear ones, not the yellow ones) by Farnam (I will have them available on the www.morganequine.com store soon) and an Alysinite Trap sold at IPMlabs.com are the 2 best traps to have according to a very nicely done paper I read. The Alysinite trap has replaceable sleeves so they are very cost effective, but if you want convenience, go for the the Farnam product. At Morgan Equine Veterinary & Farrier Hospital we use the Alsynite traps, but I will get a few of the Farnam traps (must be the clear traps) this year as well. IPM labs also carries the beneficial fly larvae.
As for the Ticks, I still recommend Equi-Spot for this purpose, just like the dog Flea and Tick topical medication. For Mozzies, you have to control the standing water around the farm. Linsay Julian gave a very comprehensive presentation about insect control in her BioSecurity lecture we had last month. The mozzie donuts and pellets are effective in standing water. Don't forget to get a few mouse traps for the feed room while your in the pest section. So...get ready for spring by stocking up on your pest supplies and getting rid of any standing water! Mud and Fly season is upon us. I'm almost OK with that as long as winter GOES AWAY.
