The BUGS are Coming, Horses Beware!

As it warms up, the bugs get active!!!
It was a long, hard, cold winter and now it is time to get outside and enjoy the weather with your horses. Unfortunately, with the spring time, bugs get active and irritate you along with your horse that is continuously outside.
Signs of damage usually show up as weakness, emaciation, anemia, rough hair coat, stunted growth, tail and mane rubbing, lesions and disease transmission. Extreme populations or transmission of disease may lead to death of the host. Here are a few examples:

Horse Bots
Horse bots  are bot fly larvae and are internal parasites of horses. The horse bot larvae develop in the stomach of horses causing symptoms ranging from stomach ulcers, and esophageal paralysis to occlusion of the digestive tract. The adult bot fly is a bee-like fly about 1/2 to 3/4 inch in length. Bot flies are covered with black and yellow hairs and do not feed as adults. In Florida two species of adult bot flies may be active throughout the year, although they are more abundant from late spring to early winter.

Horse and Deer Flies
Horse flies  and deer flies are insects that are usually daytime feeders and are vicious biters and strong fliers. As with mosquitoes only the females bite. Their attacks often account for lowered weight gains and reduction in condition. 
Because of their painful bites and frequent attacks, horse flies produce frenzied behavior in their hosts, sometimes causing them to run long distances in an effort to escape. Horse flies introduce an anticoagulant into the bite wound which causes blood to ooze for up to eight hours. These wounds are excellent sites for secondary invasion of screwworm and also cause much blood loss. Being intermittent feeders, they are known mechanical transmitters of diseases such as anthrax, tularemia, anaplasmosis, and equine infectious anemia (EIA).

Stable Flies
The stable fly, is similar to the house fly in size and color, but the bayonet-like mouthparts of the stable fly differentiate it from the house fly. Unlike the flies already discussed, both sexes of the stable fly are vicious biters. They are strong fliers and range many miles from the breeding sites.
Stable flies cause irritation and weakness in animals and account for much blood loss in severe cases. Bite wounds also can serve as sites for secondary infection and scar tissue formation. These flies are easily interrupted in feeding and are mechanical transmitters of anthrax, equine infectious anemia (swamp fever), anaplasmosis, and Habronema stomach worms.

Mosquitoes
Mosquitoes are small, two-winged flies with piercing sucking mouthparts. Females of most species suck blood, males do not. Mosquitoes attack all kinds of warm-blooded animals, domestic and wild. Florida has many species recorded as economic pests on livestock.
Although habits of different species vary greatly, all require water for the larval stage. Female mosquitoes lay their eggs on water or in places that later become flooded. Egg hatch varies with the species. Larvae (wigglers) hatch from the eggs and feed on organic matter in the water. Pupation takes place in the water. The adult mosquito emerges and is ready to feed in a short time.
Damage caused by mosquitoes include pain from the bites, unthriftiness, death by suffocation and heavy blood loss. Mosquitoes also vector such diseases as encephalomyelitis (WNV, WEE, EEE, VEE) and are suspect for many of the mechanically transmitted diseases.
If mosquitoes are a serious problem to horses, control measures should be implemented. The most effective control method available is source reduction by removing or draining mosquito breeding sites, through the activity of mosquito control districts. Daily fogging or aerosoling for adult mosquitoes may provide relief but is only a temporary control measure.

Keys To Pesticide Safety
1.     Before using any pesticide, stop and read the precautions.
2.     Read the label on each pesticide container before each use. Heed all warnings and precautions.
3.     Store all pesticides in their original containers away from food or feed.
4.     Keep pesticides out of the reach of children, pets and livestock.
5.     Apply pesticides only as directed.
6.     Dispose of empty containers promptly and safely.
Recommendations in this document are guidelines only. The user must insure that the pesticide is applied in strict compliance with label directions. The Food and Drug Administration has established residue tolerances for certain insecticides in the meat of certain animals. When these and other approved insecticides are applied according to recommendations, the pests should be effectively controlled and the animals' products will be safe for consumption.
The improper use of insecticides may result in residue in meat. Such products must not be delivered to processing plants.
To avoid excessive residues, use the insecticides recommended at the time recommended and in the amounts recommended.

  1. I was just about to post a question asking how I could put a hay bag on a timer. I've got a horse with ulcers who would greatly benefit from alfalfa every 6 hours (along with free choice timothy),horse feeders and I've been trying to figure out how I could rig something up

  2. An easy no cost slow feed for grain or similar sized feed
    is to place several smooth grapefruit sized rocks in their horse feeders. Slows them down and keeps them busy for a while….
