    Out of stock

    Resoluut Parasitic Wasps Biological fly control in dry or straw manure. Resoluut Parasitic Wasps are of the species Muscidifurax raptorellus. These parasitic wasps are natural enemies of various species of pest flies. The parasitic wasps lay their eggs in the pupae of these pest flies. The eggs hatch into larvae, which then eat the fly pupa from the inside. This interrupts the life cycle of the pest fly, and after 3 to 4 weeks new parasitic wasps emerge from the pupa. The parasitic wasps are only 2-3 mm in size and are no nuisance to humans or animals. How to use: Resoluut Parasitic Wasps come as pupae in a tube. The small package contains 15.000 parasitic wasps, the large package contains 150.000 parasitic wasps. Deploy Resoluut Parasitic Wasps at least every four weeks during the fly season (March to September).

    Resoluut Predatory Flies Biological fly control in slurry. Resoluut Predatory Flies are of the species Hydrotaea (Ophyra) aenescens. These predatory flies are natural enemies of pest flies. The predatory flies lay their eggs in the same places as the pest flies. The larvae of the predatory flies actively hunt for the larvae of the pest flies. They are so voracious that they sometimes kill more larvae than they can eat. After about a week, the predatory fly larvae pupate and new adult predatory flies emerge. The predatory flies like to stay in dark places and are no nuisance to humans or animals. How to use: Resoluut Predatory Flies come as pupae in the package. The large package with 10.000 pupae covers approximately 100 m2. Hang the package close to the problem areas but out of reach of animals. Push out the round window; the predatory flies will gradually leave the package to get to work.

    Flies cause irritation and stress in people and animals. A wide range of products is available for use on the animals in the barn. Wouldn't it be better to catch the flies before they come in from outside? You can, with the Knock Pest FlyNip Fly Trap. The natural barrier against most types of fly, reducing flies by up to 90%. Knock Pest FlyNip Fly Trap Designed on the basis of international studies and research to develop solutions for preventing flies on farms, in stables, etc. Flybuster How does it work? During the day, flies are found in sheds, barns and/or buildings looking for food (manure, feed and organic matter in general). At night, the flies leave these spaces in search of ideal conditions to rest. As they move from day to night, the flies are attracted by the irresistible smell of the attractant in the FlyNip Fly Trap and fly into the trap. The attractant is based on fermented yeast and ingredients from the food industry. The special patented 'one way' openings of the trap are designed so that once the flies have flown in, they can no longer escape. The trapped flies decompose in the trap, making it even more attractive to new flies. The trap Fit the 6 'one way' openings correctly into the trap. Fill the trap with the 240 grams of attractant supplied and add 6 litres of water. Fit the lid and place the trap at a height of 1.50 metres. Keep a distance of 10-15 metres from the object that needs to stay fly-free. When using several traps, space them 15 metres apart. It is important that the trap is in the sun and out of the wind (e.g. not near fans). The trap is ready for use! When the trap is full of flies, you can remove the flies with a sieve and top up with water if necessary. Effective for up to 60 days! REUSABLE/REFILLABLE When the trap is spent, empty it and refill it with fresh attractant and water (click here for new bait). The contents can simply be disposed of with household waste. Benefits Efficient: reduces fly nuisance by 80% / 90%. Environmentally friendly (green): no impact on the environment, non-toxic. Economical: cost-effective to use compared with other systems. Easy to use: ready-made application, ready for use. Supplied with 240 grams of attractant Mixing ratio 40 grams of attractant per litre of water.

Vliegenbestrijding rund

In a cattle barn, flies are more than a nuisance: they cause restlessness during milking and feeding and can transmit germs. This collection contains natural enemies of the stable fly from Resoluut: predatory flies and parasitic wasps that you release in the barn. That way you tackle flies in the manure, before they hatch.

How biological control works

Predatory flies lay their eggs in the manure; their larvae eat the larvae of the common stable fly. Parasitic wasps lay their eggs in fly pupae, so no new fly emerges from them. Neither does anything against the adult flies already flying around, but they curb the next generations. That is why it works best if you start before the flies really take hold and repeat throughout the season.

How much do you need?

ProductPack
Resoluut predatory fliesfor 50 m² or 100 m² of barn
Resoluut parasitic wasps15,000 or 150,000

Choose the pack of predatory flies according to the area where manure lies, such as calf pens, straw yards and deep-litter barns. Release parasitic wasps where flies pupate, such as the edges of manure areas and corners of pens. Follow the release instructions on the pack for numbers and repeats.

Points to note

You want to release live insects soon after receiving them. Do not use insecticide in the same place, because it also kills the beneficial insects. Otherwise keep the barn as dry and clean as possible: less wet manure means fewer breeding sites. This collection offers little against flies on animals at pasture; consult your vet about that.

Back to everything for cattle. For a hygienic calf shed, see calf rearing, for disinfection mats and barn supplies barn supplies, and for calm cows in the milking parlour udder care.

Frequently asked questions

Do predatory flies also work against flies on my cows at pasture?
No, predatory flies and parasitic wasps work in the barn, in places with manure. For the field you need other measures.

When do I release predatory flies?
Start before the fly problem gets going, usually in spring, and repeat according to the instructions on the pack.

Can I combine parasitic wasps and predatory flies?
Yes, they tackle different stages: predatory flies the larvae, parasitic wasps the pupae.
