Protect Property From Heron, Egrets & Bitterns

Herons, Egrets & Bitterns are long-legged freshwater & coastal birds, with 64 recognized species in the Ardeidae family. These water birds become nuisance birds when they leave large messes behind, build nests where they are unwanted, or fish in unwanted areas such as fisheries & koi ponds. Heavily protected by the Migratory Bird Treaty Act of 1918, these birds are to be treated with preventative measures only.


Found all over the world, these large birds range in size between 12" (30cm) to 60" (152cm) tall, with wingspans of up to 91" (230cm) across, & can weigh up to 11lbs (5kg). Most fishing birds are protected by the U.S. Migratory Bird Treaty Act of 1918. This means they may not be harmed, & once their nests are built, they cannot be disrupted until the chicks are old enough to leave the nest. All Bird-X products are non-lethal, chemical-free & humane, but check your local laws to be certain not to disrupt birds when they are nesting.

Bird-X offers a variety of options to keep herons & egrets out of unwanted spaces, including the sonic HeronBuster PRO device, which treats up to 7 acres with naturally-recorded predator calls combined with heron & egret distress cries. This device was created solely for the non-lethal prevention of heron, egrets, bitterns, & other waterbirds.

Koi pond owners know all about this problem, as do professional fisheries & backyard tilapia farmers. In order to keep fish unaffected, protective measures must be taken. Any property located near wetlands, marshes, shores with freshwater & saltwater bodies of water, streams, rivers & lakes may become the unwelcome location of heron & egrets landing, nesting, roosting, & perching, which can cause large messes or other problems.


All types of fish ponds are best protected by a physical barrier such as Bird Netting. Netting protects fish from being eaten by egrets, herons, bitterns, cormorants, & other birds which prey on fish, blocking off their food source; therefore eliminating, in most cases, the reason for their attraction to the property.

Birds can be much more difficult to treat if there is a food source available, so if it is possible to block off that food source, this is the first recommendation.


If netting isn't possible, such as on lakes, lagoons, or natural bodies of water, we've also had success with the Gator Guard floating decoy, which "moves" along with the water, simulating a live predator.

Herons, egrets & bitterns are colony nesters, generally choosing large trees & especially dead trees (snags) for communal nesting (rookeries). During nesting season, these larger numbers can create a lot of noise, large messes, as well as a persistent, unpleasant smell. Visual scares, including Terror Eyes or Scare-Eye Balloons, have proven successful.

For ledges, bridges, window sills, signs, or other areas that birds are perching & making a mess, the most effective method is to install either Bird Spikes (in Extra Tall) or, for especially large species, Avishock™ electrified bird track. These 2 products differ from traditional spikes because they were designed for large-sized birds. Neither product will harm birds, but will make the surface unpleasant & uninviting.
