I am aware that yellow hi-vis apparel do attract certain types of flies i.e. midges. Not aware these also attract wasps/bees, etc. I suspect your staff are not too happy with the new imposition and finding an excuse to complain about it.

RR & ss45 have got is right as far as I am aware, additionally those who wear deodorant and after shave etc. are more prone to 'investigation' by insects than non users what do your guys do and where do they do it as hotter weather is increasing the amount of insect activity throughout the UK so managers need to make appropriate arrangements NB: We had a very bad accident where a bee got inside the visor of a ride-on-mover driver whilst they were on the highway so insects can do harm

I had a similar question raised a few years back regarding bees/ wasps and hi vis. An academic from the school of biosciences at the local uni stated he had never come any issues with bees and wasps in relation to hi viz but also suggested I try the bee keepers society. By coincidence a colleague of mine is a bee keeper and member of this group. He agreed with the professor and further stated that bees espcially become irratated by dark colours (which is why bee keepers wear white) as they see them as predators. Bees and wasps will also react adversly to strong aftershaves and perfumes!!! I subsequently spoke to a H&S guy at British Sugar who have researched this issue, their findings agreed with the above. They also identified that those individuals who wore head to toe hi viz did not receive proportionately more stings to those who simply wore hi viz tabards. It might be worth speaking to these 2 groups for an update on this?

^ What he said

Do the High Viz jackets have brown hoops around them ha ha. Joking aside I know yellow attracts greenfly when they are active. Perhaps a different colour with reflective strips would be a better option.

There are Pink High Vis on the market, purchase some of these as an alternative for those complaining, I think given the choice they would prefer yellow.

If the complainers include women, they might be delighted to wear pink hi-vis items instead of yellow ones! Also, who knows, this thread might help to spur a new fashion for wearing pink hi-vis as a radical change from the boring standard yellow stuff! In fact, except in situations where an industry standard applies, e.g. orange for work on railways, a choice of colours could be offered: From a quick look on the internet, there's ample choice including green, purple, blue, raspberry, maroon and, believe it or not, navy and black!!! :-)

Go to red hiviz....most insects "see" red very poorly

Why do you think that? Are you implying that if they complain they should get a "girly" colour? Surely not

Invictus - My apologies if my comments intended in jest at #14 upset you or anyone else. Perhaps I'm still slightly conditioned by my upbringing long ago in an era when pink was still very much the traditional clothing colour for females. Nowadays, it's quite common for men, including politicians and journalists seen on TV, to wear shirts, ties and other items which are pink or somewhere in the pink area of the colour spectrum. Come to think of it, I suppose several of the shirts I used to wear at work were basically pink though their labels state 'claret' or 'wine'. That prompts me to add that marketing folk apparently reckon most people are influenced by descriptive names. Therefore, the mooted new trend for pink hi-vis might be given a boost by alternative names such as "hot neon" which is used by one or more makers/retailers!!! :-)

I work in the Water industry and over the years we have moved away from yellow hi-viz for our site operatives on sewage works because they do seem to absolutely attract the flies so much more. Orange is now the hi-viz colour of choice. One of our graduates even did an experiment on it - shame I cannot upload photos as it really is very telling.
