A few countries in the EU have been encouraging people to fix their gardens. Remove some tiles, use native/local seeds for weeds and wild flowers and let nature do its things. That seems to work. Local insect counts are going up where that happens. Even simple things like mowing strips of grass next to the roads less often seems to help. And it's actually cheaper to not mow that so often. So, win win. They'll clear it maybe a few times per year as needed.

There have been some anecdotal reports of people having to clean their car windscreens a bit more often. That's a good thing. It means more bugs are flying around. Insect counts go up, counts of anything that eats those goes up as well.

Reducing the use of pesticides is a good idea as well. If only because modern farming still depends on pesticides and pollinator populations collapsing seems to be correlated with the use of pesticides. No pollinators, no fruit/vegetables. It's in their own interest to do something about populations collapsing. Allocating some of their land for pollinator friendly vegetation would also be smart.

A lot of over the counter toxins should be banned and in EU the use and sale of those is already restricted. Even rat poison is banned in some places now. Unfortunately, farmers seem to have successfully lobbied for being able to continue to use some pesticides. But it seems that awareness of the issue is growing; including of the health effects of living close to a farm that uses pesticides. It's likely that more restrictions will come eventually.
