Cat and Dog business and Spiders

Try spritzing the most used spots with hot sauce. When they sniff and smell that they should avoid those spots, then take it from there to other spots and they may learn to avoid your sidewalk. It may take time, so be persistent, and give them time to learn. We have a neighborhood full of dogs that go on walks with their dogs, but everyone cleans up after their dogs and carry the necessary bags for this. Neighborhood sidewalks and yards stay clean and nobody has anything to complain about. I never see dead spots in the grass from them either.

For dogs I call animal control. Cats usually like dirt or sand.

CONKERS put one in each of the corners of the basement( spiders do not like conkers )and change them each year with fresh ones.

What are ”conkers”?

find those plastic grass door mats scatter a few on the sidewalk if feasible, cats wont like to walk on them

Sorry about confusion, I live in the UK conkers are the seed of the horse chestnut tree in the US ? you call it the buckeye tree.Remove the outer casing take out and pierce the seed and your good to go

Spiders don't like mint, you can make a mint spray with peppermint essential oil and water, and spray around doorways and windows to keep the spiders away! You coud also spray in the trouble spots that you tend to see the spiders! Good luck!! Happy Spider Fighting!!
