Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of rodenticide bait container, specifically relates to a bait box. BACKGROUND

[0002] The rat chisel-shaped incisors can grow throughout life, and in addition to eating, they also need to gnaw on objects to grind their teeth, often biting off power lines to cause power outages and even cause fires. At the same time, rodents can transmit a variety of rodent-borne diseases (referred to as rodent-borne diseases), such as plague, kidney syndrome hemorrhagic fever, lung syndrome hemorrhagic fever, Bolivian hemorrhagic fever, Argentine hemorrhagic fever, lassa fever, Francisella tularensis disease, tick-borne relapsing fever, Q fever, Lyme disease, leptospirosis, tsutsugamushi disease, blood fluke disease, rat typhus, toxoplasmosis, and liver fluke disease, which seriously threaten human health and life safety. Therefore, rodents are important health pests, and indicators such as their species and density are important indicators for judging the health management level of an area.

[0003] Rodents not only waste food, gnaw seedlings and crops, but also damage grasslands, so they are also the focus of the agricultural and forestry departments. For example, rice has different degrees of rat damage from sowing to tillering, booting to maturity, with losses ranging from 10-30%. Peppers, cowpeas, cucumbers, watermelons, and corns are also likely to suffer from rat damage from seedlings to harvesting, and many farmers need to replant seedlings due to rat damage.

[0004] When the density of farmland rats is greater than 10%, physical control measures and other agricultural measures are difficult to achieve the purpose of quickly controlling rat density, and baiting is the only choice. When baiting, chemical rodenticides should be used scientifically and reasonably, high-efficiency, low-toxicity, and low-residue pesticides should be selected, and safety operation procedures should be followed to prevent poisoning accidents. If the bait is directly placed on the ground, birds and other non-target animals may eat it and die, disrupting the ecological balance. Directly placing the bait on the ground can easily cause it to become moldy, and rodents may refuse to eat it, resulting in ineffective control. The remaining bait is not easy to recover after being placed directly on the ground, causing environmental pollution. Therefore, choosing a bait box to place the bait for farmland rat control will help achieve the effect of rat control while avoiding non-target animal poisoning.

[0005] Common bait boxes include cement bait boxes, ceramic bait boxes, PVC pipe bait boxes, and plastic bait boxes. Generally, the bait is placed in the middle, and when rodents eat it, a lot of bait will be exposed, making it difficult to avoid non-target animal poisoning. At the same time, plastic bait boxes are easily wet by rainwater and irrigation water, causing the bait to become moldy and deteriorate, so rodents may not eat it, making it difficult to achieve the effect of rat control. In addition, in order to prevent rainwater erosion, there are existing technologies that place the bamboo tube bait box high or on a soil pile, but this may hinder rodents from eating and affect the effect of rat control.

[0059] In use, the rat holes in the target area (e.g., fences, field ridges, ditches, and both sides of the road) can be blocked first. After a period of time (e.g., one day), the bait boxes can be buried (e.g., using a hole digging tool or a spade) along the rat path near the opened rat holes (e.g., the side of a field ditch, the side of a field ridge, both sides of a road, etc.). This can achieve precise bait placement and avoid the interference of rain and strong winds. The bait boxes can be filled with 25-50 grams of bait to effectively kill rodents. In areas with high rodent density, such as areas near village garbage dumps, bridge or crossroad vegetation, large bait boxes can be used as a fixed bait station to place bait. Each bait station can hold 1-2 kilograms of bait, and the bait can be replaced regularly to consolidate the rodent control effect.

[0060] In the specific implementation, the bait box can be buried in the ridge, without occupying the ground and affecting the movement of the field staff. The bait box can also be buried in the ridge, higher than the ground (for example, the upper edge of the bait box is 3-4 cm higher than the ground), without being eroded by rain and disturbed by strong wind.

[0061] In some specific embodiments, the bait box is preferably buried with the bottom higher than the top and the angle with the horizontal plane being 5-10 degrees, which is further conducive to avoiding rainwater from entering.

[0062] The implementation of the present application will be described in detail below with reference to the examples. It should be understood that these examples are only used to illustrate the present application and are not used to limit the scope of the present application. In the following examples, the experimental methods without specific conditions are preferred to refer to the guidance given in the present application, and can also refer to the experimental manual or conventional conditions in the art, or refer to other experimental methods known in the art or according to the conditions recommended by the manufacturer.
