Livestock Pest Protection

Livestock Pest Protection

External parasites are a production cost, not a nuisance. Cattle under heavy fly pressure spend the day bunching, stamping and standing in shade instead of grazing, and that shows up where it matters: weight gain, condition, and milk yield.

Most operations we assess are already doing something about it. The problem is usually that the something stopped working, and nobody explained why. Bug Off Pest builds livestock pest programmes across DeSoto, Charlotte, Sarasota and eastern Lee counties, with attention to the two things that actually determine whether a programme holds: the breeding source, and rotating chemistry before resistance builds.

The parasites costing you production

Horn flies are the most economically significant fly on pasture cattle in this region. They stay on the animal almost continuously, feeding many times a day, and they breed in fresh manure pats out in the paddock. A commonly used action threshold is around two hundred flies per animal, at which point production losses are already measurable. Below that, treatment costs more than it returns.

Face flies feed on secretions around the eyes and muzzle and are the primary vector concern for pinkeye. They do not stay on the animal, which changes what controls them.

Stable flies bite the legs and lower body and produce the classic bunching and stamping behaviour. They breed in wet organic matter around confinement areas, feeding sites and bale rings rather than in pasture manure, which is covered in more detail on our barn and stable fly page.

Lice and mites show up as rubbing, hair loss and poor condition, more noticeably in cooler months and in closely housed animals.

Ticks attach on pasture and around brush lines, affecting condition and carrying disease risk. Pasture and perimeter management matters as much as animal treatment.

Rodents are the quiet cost. They contaminate stored feed, chew wiring in barns and equipment sheds, and once established in a feed room they are expensive to remove.

Where livestock pest pressure originates

01

Fresh manure pats on pasture

Horn flies breed in them, and nowhere else. This is why pasture fly pressure behaves differently from barn fly pressure and needs a different programme.
02

Confinement, feeding and bale sites

Wet manure mixed with waste hay, bedding and spilled feed. Round bale feeding sites in particular produce large numbers of stable flies and are consistently overlooked.
03

Feed storage and equipment sheds

Grain, mineral and stored feed draw rodents, and spilled or spoiled feed also breeds flies and stored product pests.
04

Standing water and wet ground

Leaking troughs, poor drainage and low ground breed mosquitoes and support wet-source flies. In Florida these stay wet most of the year.

How we build a livestock pest programme

01

Site Assessment

A licensed technician walks the operation: pasture and paddocks, confinement and feeding areas, bale sites, water points, barns, feed storage and equipment sheds. We identify which species are actually driving your pressure and where they are breeding, and we review what you are already running and how long you have been running it.
02

Programme Design

Control is matched to the pest rather than applied uniformly. Pasture horn flies respond to self-treatment devices, pour-ons and feed-through products. Wet-source flies need the source dealt with plus residual treatment on resting surfaces. Rodents in feed storage need exclusion and monitoring, not bait scattered in a feed room. Where the same chemistry has been in use for several seasons, we rotate it.
03

Ongoing Service & Review

Scheduled service through the season with the programme reviewed rather than repeated. Pressure changes, resistance builds, and a programme that worked two years ago may be the reason this year is worse. All products are applied to label with the withdrawal and residue requirements for your operation accounted for.

Why Florida cattle operations choose Bug Off Pest

Agricultural work is core to what we do rather than something we take on when residential is quiet. We identify the species and the breeding source before recommending anything, we manage chemistry rotation so a programme keeps working, and we cover the whole operation including the feed room and equipment sheds most pest companies never look at.

Frequently asked questions

My fly tags used to work and now they do not. What changed?
Almost certainly resistance. Horn fly resistance to pyrethroid ear tags is well documented and it builds where the same class of chemistry is used season after season. The fix is rotating to a different class rather than increasing the dose, and removing tags at the end of the season rather than leaving them in, since expiring tags expose flies to sub-lethal doses and accelerate the problem.
They work on horn flies, because the active passes through and prevents larvae developing in the manure. Two limitations are worth knowing. Every animal in the group has to be consuming it consistently, which is difficult with free-choice mineral. And it does nothing about flies breeding in your neighbour’s manure across the fence. It is a good component of a programme rather than a complete answer.
Products are selected and applied to label, and label requirements for withdrawal, milk residue and animal class are followed. Dairy operations have specific restrictions around milking areas and lactating animals, and we account for those at the assessment. Anything relating to animal health treatment rather than premise pest control is a conversation for your vet.

Yes, and it is usually the part of an operation getting the least attention. Rodents in a feed room contaminate stock, chew wiring in equipment sheds and breed quickly with a permanent food source available. We handle it with exclusion and monitoring rather than loose bait around feed.

Fire ants are a genuine hazard to newborn calves and to anyone working the ground, and mounds also damage equipment. They are treated differently from flies, at the mound and through broadcast application at scale. We cover that on our pasture and commercial fire ant page.
