(b) a removable top bonded to the upper rim for sealing the interior of the tray body; and (c) a powdered plant treatment agent in the interior of the tray body and supported on the base when the tray body is upright. ## Claims ### Claim 1 A replaceable tray for inserting into an exit path of a bee hive, the replaceable tray comprising: a) a tray body having a base and at least one side wall extending upwardly from the base and surrounding a periphery of the base, the base and the at least one side wall defining an interior of the tray body, and the at least one side wall having an upper end defining an upper rim of the tray body; b) a removable top bonded to the upper rim for sealing the interior of the tray body; c) a powdered plant treatment agent in the interior of the tray body and supported on the base when the tray body is upright; wherein the tray body has a bee entrance end and a bee exit end opposite the bee entrance end, and the at least one side wall includes an entrance end wall at the bee entrance end and an exit end wall at the bee exit end, each of the entrance end wall and the exit end wall defining a set of steps between the base and the upper rim for permitting bees to walk between the base and the upper rim, wherein the entrance end wall defines a first set of steps leading downwardly from the upper rim to the base, and the exit end wall defines a second set of steps leading upwardly from the base to the upper rim. ### Claim 2 (depends on 1) The replaceable tray of claim 1, wherein the tray body has a first end and a second end opposite the first end, and wherein the tray body is generally symmetrical to permit the tray to be nested in a receptacle of a bee domicile in either of a first orientation, in which the first end acts as a bee entrance end and the second end acts as a bee exit end, and a second orientation, in which the first end acts as the bee exit end and the second end acts as the bee entrance end. ### Claim 3 (depends on 2) The replaceable tray of claim 2, wherein the tray body extends widthwise along a lateral axis between a first side and a second side, and the tray body is generally symmetrical about a vertical plane intersecting the lateral axis. ### Claim 4 (depends on 2) The replaceable tray of claim 2, wherein the tray body extends lengthwise along a longitudinal axis between the first end and the second end, and the tray body is generally symmetrical about a vertical plane intersecting the longitudinal axis. ### Claim 5 (depends on 1) The replaceable tray of claim 1, wherein the tray body has a bee entrance end and a bee exit end axially opposite the bee entrance end, and the interior has a length between the bee entrance end and the bee exit end, and a width perpendicular to the length, and wherein the length is greater than the width. ### Claim 6 (depends on 5) The replaceable tray of claim 5, wherein the length is at least 1.5 times the width. ### Claim 7 (depends on 1) The replaceable tray of claim 1, wherein each step is defined by a vertical rise, and a magnitude of the vertical rise for each step is generally the same. ### Claim 8 (depends on 1) The replaceable tray of claim 1, wherein each step is defined by an axial run, and a magnitude of the axial run for each step is generally the same. ### Claim 9 (depends on 1) The replaceable tray of claim 1, wherein the tray body is of integral, unitary, one-piece construction. ### Claim 10 (depends on 1) The replaceable tray of claim 1, wherein the tray body is formed of plastic and is moisture impermeable. ### Claim 11 (depends on 1) The replaceable tray of claim 1, wherein the removable top is moisture impermeable and light impermeable. ### Claim 12 (depends on 1) The replaceable tray of claim 1, wherein the removable top is bonded to the upper rim via a heat seal. ### Claim 13 (depends on 1) The replaceable tray of claim 1, wherein the removable top comprises a metal foil. ### Claim 14 (depends on 1) The replaceable tray of claim 1, wherein the removable top carries an electrostatic charge for repelling the powdered plant treatment agent to inhibit sticking of the powdered plant treatment agent to the removable top. ### Claim 15 A bee vectoring kit, comprising: a) a bee domicile body having an interior for colonization by bees, the bee domicile body having a domicile entrance and a domicile exit through which bees enter and exit the domicile body; b) a domicile lid removably receivable on the domicile body, the domicile lid including a downwardly extending receptacle, the receptacle including a receptacle entrance port open to the domicile body and through which bees enter the receptacle from the domicile body, and a receptacle exit port through which bees exit the receptacle, the receptacle exit port in alignment with the domicile exit; and c) at least one replaceable tray nestable in the receptacle between the receptacle entrance port and the receptacle exit port, the replaceable tray including: i) a tray body having a base and at least one side wall extending upwardly from the base and surrounding a periphery of the base, the base and the at least one side wall defining an interior of the tray body, and the at least one side wall having an upper end defining an upper rim of the tray body, the upper rim of the tray body at an elevation below the receptacle entrance port and the receptacle exit port when the tray is nested in the receptacle; ii) a removable top bonded to the upper rim for sealing the interior of the tray body; and iii) a powdered plant treatment agent in the interior of the tray body and supported on the base when the tray body is upright. ### Claim 16 (depends on 15) The bee vectoring kit of claim 15, wherein the tray body has a first end and a second end opposite the first end, and the tray body is generally symmetrical to permit the tray to be nested in the receptacle in either of a first orientation, in which the first end is adjacent the receptacle entrance port and acts as a bee entrance end of the tray and the second end is adjacent the receptacle exit port and acts as a bee exit end of the tray, and a second orientation, in which the first end is adjacent the receptacle exit port and acts as the bee exit end and the second end is adjacent the receptacle entrance port and acts as the bee entrance end. ### Claim 17 (depends on 15) The bee vectoring kit of claim 15, wherein the tray body has a bee entrance end and a bee exit end opposite the bee entrance end, and the at least one side wall defines a first set of steps at the bee entrance end leading downwardly from the upper rim to the base to permit bees to walk down from the bee entrance port to the base, and a second set of steps at the bee exit end leading upwardly from the base to the upper rim to permit bees to walk up from the base to the bee exit port. ### Claim 18 (depends on 15) The bee vectoring kit of claim 15, wherein the tray body has a bee entrance end positionable adjacent the receptacle entrance port and a bee exit end axially opposite the bee entrance end and positionable adjacent the receptacle exit port, and the interior has a length between the bee entrance end and the bee exit end, and a width perpendicular to the length, and wherein the length is greater than the width.
