well something is very wrong. i leave the greenhouse door open too allow bees and bugs in too feed on my veg's flowers.

over three days i have noticed dead honey bees, stone dead normaly in the mornings and early evenings. i have two main veg in flower( cucumber/dwarfbeans). in all 11 dead bee's in 3 days and also around 6-6 head hover flys ( mini wasp looks like).

im kinda worried on what is the problem, why do these bee's die in my greenhouse, what could be the problem, could my plants be the problem.

i dont use any weedkiller/pest control products i try and use nature own beasts and my hands for snail and larger beast removal. so i know it cant be chemicals i dont use them.

do we have any budding/pro/expert bee keepers about please ? and could sorta help me work out why the bee's visiting are being killed.
