Planning and control of fly / larvae infestation

Successful fly control always consists of controlling the adult fly and the fly larvae. Only the regular and simultaneous control of all developmental stages of the fly brings the desired success.

These agents act on the adult flies and kill them quickly. The active substances affect the central nervous system of the flies and prevent the transmission of vital information. The rapid generation change can lead to the development of resistance. This means that the flies are only killed by higher doses or are completely immune to an active ingredient. To prevent this, the active ingredient and active ingredient group should be changed regularly.


Larvicides act on the moulting of larvae during the transition from one larval stage to the next (so-called growth regulators). This process is very specific to insects. These products are therefore harmless to humans and warm-blooded animals. At present, no resistance problems have arisen in the control of stable flies. However, pay attention to the correct dosage here as well.

The right timing matters when it comes to fly and larvae control!

When is the right time for treatment or how do you achieve the best success?

Fly larvae

Control the fly larvae and you control 80% of the problem
As soon as the temperatures rise in spring, fly development hardly begins to be noticed. Because the development from egg to adult fly takes place much earlier, control must be thought of before the warm season begins.

Successful fly control primarily involves brood control of eggs and larvae, because adult flies only make up about 20 percent of the total population.

Eggs and larvae thrive particularly well on manure, slurry and fodder residues in warm, humid climates. Often, if you look closely, you can see the larvae as small white "worms".
1 kg of manure or residual feed is enough for the development of up to 10,000 maggots!

Typical breeding sites include under pen partitions, underneath feed troughs, on wet spots underneath the drinker, on feed residues, on floating layers in the slurry channel and on manure.

The basis for success is thorough distribution on the manure area using a watering can or backpack sprayer and regular application:
  • First treatment approx. 3-5 days after stabling or manure removal.
  • Second application after 2 weeks
  • In routine approx. every 4-6 weeks
Special products to control fly maggots in manure, slurry or bedding inhibit the growth of fly larvae by influencing the moulting of the larvae. Pupation is prevented. The larvae die before the flies hatch. The development cycle of the fly is interrupted
