Muscidifurax raptorellus, Muscidifurax zaraptor, and Spalangia cameroni are tiny wasps that don't bother humans, but parasitize the pupae of many species of flies found in areas with livestock, breaking the life cycle of the flies.

You cannot place too many parasites. You can place too few. For dairies, feed lots and horse stables, we recommend between 300 and 500 parasites per animal per month during the fly season (March to October or November depending on weather). For confined hog operations, this number will be between 200 and 400 parasites per animal per month. Chickens require from 1 to 5 per bird per month. If your fly problem is very severe, these numbers should be increased; the first and second releases especially should be doubled or tripled.

  • Begin release program as soon as the weather begins to warm up.
  • Flies reproduce at a faster rate than the the fly parasites, so reintroduction on a regular basis is important.
  • Release every 1- 4 weeks during all warm months, generally March or April (once temperature reaches 80°F) through October.
  • For later starts, double the rates for the first 2 releases.
  • Use in conjunction with PVF&GS Fly Trap for best results.

Using predatory wasps to control fly populations in farms and gardens is a fascinating and environmentally friendly approach to pest management. This method, part of an agricultural practice known as biological control, harnesses the natural predator-prey relationships to maintain pest populations at manageable levels.

The concept of biological control dates back to ancient times, but it wasn't until the late 19th and early 20th centuries that the practice began to gain scientific backing and widespread acceptance. One of the early successes of biological control was the introduction of the Vedalia beetle to control cottony cushion scale in California citrus orchards in the 1880s. This success paved the way for further exploration into using natural predators to control pests.

Predatory wasps, belonging to various species, play a significant role in controlling fly populations. These wasps are not the typical wasps that people generally fear; they are often smaller and less aggressive towards humans. Instead, they are formidable predators of various insect species, including flies.

There are different types of predatory wasps used in controlling flies. For example, some species of the genus Spalangia are known to parasitize fly pupae. These wasps lay their eggs inside the fly pupae, and the developing wasp larvae consume the pupae from the inside. Another example is the genus Muscidifurax, which also targets fly pupae. The use of these wasps is particularly prevalent in animal farms where flies can be a significant problem, spreading diseases and causing distress to livestock.

The introduction of predatory wasps into a farm or garden ecosystem is a delicate process. It requires a thorough understanding of the ecological balance and the life cycles of both the predator and the prey. The goal is to establish a sustainable population of wasps that can effectively control the fly population without causing harm to other beneficial insects or the overall ecological balance.

One of the significant advantages of using predatory wasps is the reduction in the need for chemical pesticides. Traditional fly control methods often involve the use of chemicals that can be harmful to the environment, beneficial insects, and even humans and livestock. Biological control, on the other hand, is a more sustainable and eco-friendly approach.

However, the effectiveness of predatory wasps can be influenced by various factors such as climate, the availability of prey, and the presence of other predators or competitors. Farmers and gardeners need to monitor the situation closely and may sometimes need to reintroduce wasps or adjust their strategies.

In recent years, the practice of using predatory wasps has gained popularity, particularly in organic farming, where the use of chemicals is limited. Research continues to evolve in this field, with scientists exploring the potential of different wasp species and developing methods to enhance their effectiveness and sustainability.

The use of predatory wasps in controlling fly populations represents a fascinating blend of ancient practices and modern scientific understanding. It exemplifies a shift towards more sustainable and environmentally friendly agricultural practices, highlighting the importance of understanding and working with natural ecosystems rather than against them.

Helps clear my sinuses
Color: White, Color: White
As someone who would constantly wake up in the middle of the night with a cough and stuffy nose, I have had this air purifier for 1 day and have already slept through the night with completely clear sinuses! It is almost noon the next day and I have not had to blow my nose or clear my throat once, which is unheard of for me. My stuffy apartment smells better too. I haven’t even dusted or vacuumed yet and it is already making a huge difference in my daily life, I can’t wait to do a deep clean on top of it! It really works and is 100% worth the money!

No complaints
Color: White
I have purchased three of these air purifiers. We keep one in each occupied bedroom and one in the living area. I appreciate that they don’t take up much space. They are easy to operate and are aesthetically pleasing enough. We purchased to help with our dog’s dander and any loose mold spores that may be in the air. I put one in our laundry room for awhile because of the musty smell that hung in the air. The next time I walked in there I could feel the difference. It smelled lighter and felt drier than before. The first two I began using at the same time, and I’ve had to change one filter so far. It lasted approximately 2 months. It was dirty when I removed it which indicates it is functioning properly. They are also pretty quiet. I can sleep with it on low next to my head without issue, but it does have a sleep mode. Overall, I have no complaints and would recommend for an affordable air purifier. Update: The third one we purchased separately from the first two. When the unit is ON but not RUNNING it has this incredibly high pitched frequency that is similar to your ears ringing. I haven’t noticed any issues with its functionality, but I definitely make sure I unplug it when not in use.

Great value for $$$
Color: White
This is a great air purifier! We had some work done in our master bathroom & really wished we would have purchased this sooner! We lived in the house during the remodel, but so much junk is circulated in the air since demolition of our 60 year old home! Both my husband & I have had respiratory infections! Glad this helped clear the air so we could sleep better at Night!!
