The SHB is already resident in many countries around the world including the USA and Australia.
Now an established resident in parts of Italy it will unfortunately arrive in other parts of Europe.
Female Beetles deposit clusters of eggs in clusters of 10 – 30 in comb and crevices they may also open sealed cells to lay eggs The eggs are pearly white, and approximately 1.4mm long and 0.26mm wide, about 2/3 the size of a honey bee egg.
Eggs Hatch within 2 to 4 days and start to feed on honey, pollen eggs & brood
Larvae become mature
in 7 to 10 days. Larvae exit the hive and burrow into the soil around the hive
Beetles larvae pupate in the top 4″ of soil depending on conditions this takes 3 to 6 weeks on average
Newley emerged beetles find a host colony by there smell.
beetles can also fly to hives and also leave with
Adult beetles like dark confined spaces in the hive in corners and cracks and can often be found hiding in the corners of the hive a lid.
There are SHB traps to catch the adult beetles but as far as treatment its more a case of careful control to keep numbers at a minimum.
