Poison baits

In contrast to the controlled use of these compounds in the neighborhood of farms and human habitation, they have sometimes been used in a less controlled way against rodents and vertebrate predators, which causes problems in conserved areas. In a number of conserved islands in New Zealand, for example, bait containing brodiphacoum has been used for rodent control, both at bait stations and by aerial distribution (Eason et al. 2002). In the latter case, poisoned bait is freely available, and herbivores and omnivores, as well as predators and scavengers are at high risk. This problem will be discussed further in Section 11.6. [Pg.223]

Used industrially in poison baits to control rodents, wild pigs, and predators. [Pg.325]

Deaths of nontarget species of birds after eating 1080-poisoned baits have been reported (Spurr 1979 Mcllroy 1984 Fry et al. 1986 Hegdal et al. 1986 Mcllroy et al. 1986a), although population effects have not yet been demonstrated. Birds of several species were found dead after 1080 baits were applied to kill California ground squirrels (Spermophilus beecheyi), but only Brewer s blackbird... [Pg.1428]

Sodium molybdate and other molybdenum compounds in toxic baits have potential for termite control (Brill et al. 1987). Baits containing 1000 mg Mo/kg were fatal to 99% of the termite Reticu-litermes flavipes in 48 days. After 8 to 10 days, termites became steel-gray in color, but appeared otherwise normal. Mortality began only after day 16. Termites did not avoid the poisoned bait, even at concentrations of 5000 mg Mo/kg. Yoshimura et al. (1987) reported similar results with another species of termite sodium molybdate killed 100% of the workers in a colony of Copotermes formo-sanus within 24 h after eating filter paper treated with a 5% solution. Some other species of insects — including fire ants (Solenopsis sp.) and various species of beetles and cockroaches — were not affected when exposed to baits containing 5000 mg Mo/kg for 48 days (Brill et al. 1987). [Pg.1557]

Many birds such as sparrows, blackbirds, rice birds, grackles, and cowbirds can cause heavy loss of grain in rice fields. Because the use of poisoned baits in some countries is often restricted by law or popular opinion, the information presented does not constitute a recommendation on any specific chemical. The use of strychnine-poisoned rough rice (17, 18, 25) against blackbirds, grackles, cowbirds, and English sparrows, wherever the use of poison is permitted, can be effective. Many other toxic chemicals will kill these birds however, domestic poultry and game bird species are relatively much less susceptible to strychnine than to other toxic materials. Therefore, we have in strychnine a fairly effective selectivity which other toxic materials do not offer. [Pg.70]

These materials, as well as more recent poisons like zinc phosphide and fluoroacetic acid, work as acute rodenticides and can be effective when a rodent consumes a lethal quantity of poison in a single dose in its food or drink. Unfortunately, animals often consume less than a lethal dose, which produces side effects which the animals associate with the bait. The result is that they become "bait shy" and are likely to be wary of the same poison bait a second time. [Pg.45]
