Sally,
Squash and pumpkins are easy to hand-pollinate since the male and female flowers are close together. We use a q-tip.
We're surrounded by commercial agriculture (corn mostly) and have no control over what chemicals the farmers use. We have lots of clover and honeybees are particularly attracted to it. We've seen very few this year. While we don't currently have a problem with the mosquitos that carry the Zika virus, a lot of beekeepers through the country have had serious bee losses due to indiscriminate spraying by many mosquito control agencies trying to eradicate them.
