Avitrol is used as a chemical frightening agent to remove pest birds from a given location. Avitrol as applied is a chemically treated grain bait. Birds eating the treated bait will be affected in a manner that, varying by species, will artificially cause them to emit distress and alarm cries and visual displays used by their species when they are frightened or injured. This may include flying erratically, vocalizing, trembling, dilation of the pupils and other symptoms indicative of loss of motor control. This will frighten the flock and cause it to leave the site. In laboratory testing, if the dose is lethal, death will usually occur within an hour following. Not for Sale to Rhode Island

Target Pests

Blackbird Cowbird Crow Grackle House Sparrow Pigeon Starling


Both baiting and prebaiting is best done at sunrise. Birds will eat more at their first feeding than any other time of day. The bird's metabolism is at its highest in the morning and as a result will succumb to Avitrol Treated Grain more readily. In laboratory testing, if the dose is lethal, death will usually occur within an hour following administration. If the dose is sub-lethal, there will be a recovery period which may be as short as 4 to 5 hours. Surviving birds have no lasting effects from 4-aminopyridine. Always follow all directions on the Avitrol label(s), (including, but not limited to, those already there for blending and placement of baits) for the product being used and the specific pest bird.

How much of a dose do you use per placement of avitrol? 1 cup, 2...
A shopper on Sep 7, 2017
BEST ANSWER: To obtain minimal mortality, limit the distribution of Avitrol Whole Corn to scattered spot placements that will provide feeding opportunities only for the
necessary number of target birds. After the birds’ feeding pattern has been established through pre-baiting, replace untreated bait with diluted
treated bait only at sites where the target birds are actively feeding. Do not apply treated bait to inactive feeding sites. Where uneaten bait may be a
hazard to other birds or animals, it must be picked up at the end of each day. When this product is used in or around occupied buildings, pick up and
dispose of dead birds by burial or incineration. This product must not be applied where non-target bird species are feeding. When baiting with Avitrol
Whole Corn, best results are usually obtained by rotating pre-baiting (with untreated bait), with baiting, (with blended bait), until the desired control is
obtained. Note that retreatment may also be necessary after rainfall.
Does the repellant wear off or will the bird permenantly have those debilitating symptoms?
A shopper on Aug 18, 2017
BEST ANSWER: Yes, it will wear off in 4 to 6 hours, but should cause enough distress to frighten flocks away. You will continue to bait until the desired effect is reached.
What states allow for this product to be utilized?

BEST ANSWER: This requires a applicators license, and here is the link to the registered states.

It does work!
I was a little skeptical of using this product, partly because of the cost and I have a HUGE bird problem in my sheds. Ordered the smaller size and tried it out. The birds moved out and there were dead ones on the ground. Unfortunately, they moved into the shed next door which I can't poison the same way because of livestock. I would recommend this product!

Bye bye birds!
I love this product and it worked great! I was a bit skeptical about this product while searching for something to repel birds that have been gathering outside my yard and making nests on my house. I laid this stuff out and within days those birds stopped hanging around.
