General note on chemicals: I do not endorse or advise on chemical treatments, as I am not qualified to do so and there may be dangers beyond my control. New products may be introduced or existing ones withdrawn, so it is difficult to keep up with current information on a website such as this. As many of the chemical pages were generated by Dave Cushman, I am leaving the content mainly as left by Dave for historical purposes only, which may mean information is out of date and unreliable. The user should seek guidance from other sources and satisfy themselves regarding safety and legality. Roger Patterson.

Burn Strips, more properly called... smouldering strips, these are known as 'Dol' strips as they are produced in the Czech Republic by The Bee Institute at Dol. They are for the fumigation of beehives with chemicals that are evaporated by the smouldering action of the strips. The strips themselves are 25 mm wide, 90 mm long and 0.65 mm thick. (illustrated left)
The strips are packed in quantities of 50 and are packed in a polythene bag as the right hand picture shows. A fold of card is stapled over the folded top end of the bag. This card has details on the rear that are similar to the white paneled illustration below. The pictures on the Czech version are in black and white, the coloured ones are due to a bit of my artistic licence, but mimic the originals.

The strips are impregnated with an oxygen producing chemical and they smoulder in a repeatable and controlled manner, at a temperature that is suitable for the evaporation of the chemicals concerned.

The text in the above panel has been adjusted for an English speaking readership, but some of the quaint translation has been left to give the 'flavour' of the original. The strips must only smoulder, if they flare up they must be blown out.
