16 ,,,,,,, Propolis <br /> J f2 The inside of hive bodies has traditionally been smooth. However, if the insides 411 <br /> /'% L of the boxes are made from unfinished, very rough lumber the bees will deposit <br /> propolis, or tree resins, inside the boxes as a propolis envelope, as they do <br /> naturally within tree cavities. The resins are antimicrobial, and research at the <br /> Biology University of Minnesota Bee Lab shows that a propolis envelope benefits honey bee <br /> l�. immune systems, microbiomes, disease prevention, and overall colony health. <br /> Box <br /> Painting Equipment <br /> The exterior of the hive boxes should be smooth before they are painted. All exposed parts of the hive should <br /> be covered with a coat of exterior primer, followed by one or two coats of good quality exterior latex paint. <br /> Painting the outsides of your hive boxes protects them from rotting and warping, prolonging their usability by <br /> many years. Use a good quality brush or roller to make painting easier. There is no reason the exterior cannot <br /> be decorated in any way you want. If the colony will be in the sun, avoid dark colors. Oil-based paint can be <br /> used to decorate the outside of the boxes, but too much prevents the box from breathing and the oil paint may peel. <br /> You may use other paints, stains, or wood preservatives as long as you make sure they do not contain any <br /> ingredients that will be harmful to the bees. Do not paint the inside of the boxes. <br /> Components of a Hive <br /> See an example of a hive with a full set of equipment in Figure 21. • <br /> -.01— Telescoping Cover <br /> -.411110011111"- f— Inner Cover <br /> • Honey Super <br /> . <br /> • <br /> I -f-- Frame <br /> • <br /> • .• ; 4 Hive Body <br /> • <br /> • • <br /> • II. • <br /> 00 ...; -41— Bottom Board <br /> •• f- Hive Stand <br /> • <br /> roll. <br /> i <br /> Figure 21.Typical Entrance Reducer <br /> Langstroth hive. <br /> Beekeeping in Northern Climates 20 <br />
