Our preference at Spalding Labs for a pesticide spray is UltraShield® Red. We like this because it is the newest fly spray on the market (introduced in 2011), it has 5 active ingredients (Pyrethrins,Pyrethroids, Permethrin, Cypermethrin, Tetramethrin) which is more than others, and it’s effective against a very broad spectrum of nuisance insects including Mosquitoes, Gnats, Ticks, Wasps, Horse and Deer Flies, No-see-ums, Chiggers, Fleas, Culicoides and more, as well as regular House Flies and Biting Stable Flies.
UltraShield Red is also a premise spray for fly resting areas as well as cracks and crevices to keep crawly bugs out. So it is more versatile than most other fly sprays. Spraying fly resting areas on warm south facing walls when cool, or shady area when its hot, can be very effective to kill pest flies. This does not bother Fly Predators as they will never be on those areas. UltraShield products are water based so there’s no oily residue on your animals.
It makes much more sense to buy Ultrashield® by the gallon rather than a quart. You’ll save over 30% and chances are you’ll use a gallon’s worth sooner or later. Its shelf life is 5 years.
With your first gallon from us you’ll also get at no cost two exclusive items that will make it easier and safer to apply spray. The first is an advanced spray bottle ($10 value) with a finer mist that works in any position. The second is a pump applicator for the gallon bottle that easily refills the sprayer. You’ll only get these free items from us!
