Lots of people have chickens in their back gardens. Not to mention rabbits etc.
There are some vegetables which are best left to the professionals; though some gardeners will disagree. Celeriac, swedes, fennel, mushrooms.
Would that it was as simple as removing bird feeders. If you have livestock, you will have rats. Mostly they go underground to die, though we did have a dalmation which was an excellent rat-catcher - no poison involved.
Yes, I have given the advice before. I wonder what you think professional rat-killers would do to get rid of the rats?
Please give your advice to rid the OP of rats, without harming the local wildlife.
If you want to put out poison, put it in the centre of a length of drainpipe and lay it down where they run. Nothing can get at it then, except the rats.
Why not look on a good bulb web site where they illustrate every bulb they sell? I'm sure a picture will jog your memory.
Can be eaten raw, shredded in a salad too.
However hard you prune (Growth follows the knife) the shrubs will always win.
The weed-killer must be applied to green growth. It won't do anything to roots. I am talking of normal Glyphosate. Do not apply to anything before the weather warms up. Anything you spray must be growing well.
Re. the potatoes under the bed. Quite the wrong place; they should be in the light.
