I've seen birds and squirrels take strawberries. But I have no problems sharing my harvest with the wildlife as long as they don't take them all. I also have slugs and pillbugs(also called potatoes bugs or woodlice) eat some strawberries. Again, they only damage a small portion of berries so I don't worry about it. For my plants the first year or two was the worst. Now I get so many strawberries I don't worry about the few I've lost. I do use DE sometimes if I need to and it helps with some insects. For animals like deer and squirrels I make up a hot pepper spray. It will not work for birds. Birds don't get that hot burning sensation that mammals do. But the spray is simple. The hottest hot sauce I could find, mine has ghost chillies. Mix some, probably a tablespoon or two with a couple of cups of water, a few drops of dish soap and an egg. Sometimes I also add some chilli powder too. I don't do exact measurements. Mix it all together and strain with a mesh sieve. Spray plants as needed and after rain. You will have to wash the berries good before eating unless you like hot strawberries. I've found that the animals learn quickly and you will not have to apply this much after they get a taste. In fact the deer have left my yard alone, I haven't had to spray at all this year and very little last year. Even though all the houses around me had deer stripping their gardens. I personally would not put out glue traps. They animals will die a slow painful death if they get them stuck on them. I have no problems with killing them if that what is needed. But IMO, do it quickly.
