Automatic Barn Fly Control With Aerosol Dispensers: Pros & Cons

Barn fly control is a tedious but essential part of the life of any barn owner. Whether you have cattle or horses, flies can be an absolute plague, especially during the hot summer months. Fortunately, there are a lot of barn fly control systems you can use. Unfortunately, having a ton of options tend to just make the choice harder. And even more, unfortunately – all these barn fly control systems come with their own unique sets of advantages and disadvantages, a lot of which are mostly subjective and related to different situations in different manners.

So, why covering every single method for barn fly control at the same time is impossible, we can start by looking at one of the more popular barn fly control methods – automatic aerosol dispensers. What are these devices and what are their exact pros and cons?

Simply put automatic aerosol dispensers for barn fly control are automated fly spray systems that are meant to keep your barn free of flies with minimum supervision and effort on your part. These automatic fly spray devices typically work on batteries, have containers that need to be filled with a specific type of barn fly spray, and they sport a fancy programmable interval spraying mechanism that will release said spray on specific intervals, usually 7.5, 15, 30 or 60 minutes.

Of course, there could be multiple variations depending on the exact type of horse barn fly spray system you are looking at but these are the general principles – automatic fly spray system are electronic spray containers that can be programmed to automatically release the spray into the air at specific intervals.

So, all this sounds fine and dandy, but what are the exact pros and cons that follow from this brief description? Well, let’s break them down:

Pros:

  • Barn fly spray systems require minimum supervision. Gone will be the days, with such a system, that you’ll have to spend hours each day chasing, killing and spraying flies in your barn manually. With most good, high quality fly misting systems for barns you will be able to just set them up and forget about the fly problem almost entirely. Sure, you’ll need to change the device’s batteries every once in a while as well as load it with fly spray again, but aside from that, you will be free to focus on your other work.
  • When they are well-positioned, automatic barn fly control aerosol dispensers can easily maintain a steady and consistent aerosol mist in your barn and make sure that there aren’t any corners or sides that aren’t being treated.

Cons:

The cons of these automatic barn fly control dispensers are where things start to get controversial as a lot of people swear that most of these cons are false, while there are a lot of other indicators that seem to point us into the other direction. Either way, controversies aside, here is how we see things. We’ll start with the more mild and non-controversial cons:

  • At the end of the day, automatic spray dispensing systems are just automatic sprayers – if you keep them stationary and if you haven’t chosen the right locations for them, there is a risk that they aren’t distributing the aerosol mist evenly across your barn. In other words, you might get corners or pockets with flies because the mist hasn’t reached them or you might have to manually spray in certain places to avoid this problem.
  • As convenient as they are, automatic aerosol dispensers are electronic devices so they require a fair bit of maintenance – they need to be well-preserved, their batteries need to be changed, you will need to make sure that their electronics are working properly, and so on.
  • The main drawback of automatic barn fly aerosol mist dispensers, however, is not in the devices themselves, it’s in the aerosols they use. As such, it feels a little silly listing this is a “con” of the devices but considering that most such automatic dispensers are made to work with specific aerosols only, the two go hand in hand.
  • So, what’s so bad about the barn fly control aerosols that these automatic dispensers use? Well, this is where things become controversial – a lot of people and active customers swear that these aerosols are safe for your barn animals and even for humans. A lot of other customers claim that they are generally safe for barn animals but are hazardous for humans or for pregnant barn animals. And then there is everyone else who is of the opinion that these aerosols shouldn’t be used around any mammal that you care about.
  • But what do environmental protection agencies or the manufacturers themselves say about this whole issue? If you contact any of your local government’s environmental protection agencies chances are that they will just tell you to follow the instructions on the label to the letter. And when you do that and take a more careful look at said instructions, virtually all of them state that these barn fly aerosols shouldn’t be used in the presence of people, pets or food, as well as that all premises should be ventilated before and after the aerosol has been used.
  • So, what this means is that if we are to use barn fly aerosols in our barns, we will need to vacate the premises every time we spray. And if we are using an automatic barn fly control aerosol dispensers that sprays said aerosol once every 10 minutes, the barn will need to be empty at all times. Instead, what sounds like a much more logical solution is to apply an aerosol solution a couple of times manually while the barn animals are outside which would render the automatic dispensers pointless.

At the end of the day, the judgment on the automatic spray dispensers depends on the judgment on the aerosols themselves. If the aerosol agent that your dispensers are going to dispense into the air is safe to use around barn animals then you should have no qualms about doing so. Otherwise – we would advise against it.
