Start finding flies and mosquitoes in my yard, which I'm sure is caused by those wild cats pooping everywhere.
Bought Deltamethrin (from Bayer, 25g/L) and Cypermethrin (from BASF, 100g/L).
Bayer said it should be used indoor, but it looks like the chemical itself is stable enough under sunlight. BASF said you can use it anywhere you want.
Besides, I also looked up and got a conclusion that both chemicals are not danger or harm to birds. For cats, they are toxic, so I'll kick out the cats before I use them and hope they don't come back and lick the floor.
But consider I'm not in major of chemical stuff and didn't go that deep into the details (just read what Google offers to me). So just want to ask if I'm right. Although I don't like those wild cats invading my yard, still don't want to poison them. Also the bird, I want to be safe to them.
One source I read about Cypermethrin said this chemical will paralyse birds, but other source said it's generally non-toxic to birds. So I need to check it before I use it.
