Tamper resistant weighted rodent and insect bait station

1. A bait station, comprising:

an enclosure for bait accessible to an animal, the enclosure having a periphery and two vertically-extending lip edges surrounding a substantial portion of the periphery, the enclosure having a bottom and a sidewall formed integrally with the bottom and extending upward from the bottom, the lip edges disposed at an upper end of the sidewall, the enclosure also having a doorway in and encircled by the sidewall, the bottom including a planar portion configured to be coupled to a weight such that the weight can be supported by a non-vertical surface with the planar portion of the bottom parallel to the surface; and

a lid pivotally coupled to the enclosure and securable to the enclosure to define together with the bottom and sidewall of the enclosure an interior section of the bait station accessible to animals when the lid is closed, wherein a lip edge of the lid fits between the two lip edges of the enclosure when the lid is closed such that an outer surface of the lip edge fits closely adjacent to one of the two lip edges of the enclosure and such that the lip edge of the lid is positioned outside of the interior section of the bait station;

where the enclosure has a maximum height and the lid has a maximum height that is less than the maximum height of the enclosure, the maximum height of the enclosure and the maximum height of the lid each being perpendicular to the planar portion of the bottom when the lid is closed.

2. The bait station of claim 1 , further comprising a receptacle securable to the enclosure for holding material to weigh the bait station.

3. The bait station of claim 2 , wherein the receptacle is removably securable to the enclosure.

4. The bait station of claim 2 , wherein the receptacle is securable to the enclosure by one or more mating tongue and groove mechanisms.
