How did I miss this thread?! Great Dane, You do think up the neatest threads.
peppermint, lavender or citrus smells will keep spiders away. Also, interestingly enough I've read that chestnuts keep spiders away! you don't need to crush them or anything, just set chestnuts in dark corners, or on a windowsill and spiders will stay away!
I do know that putting some lemon oil in a spray bottle and diluting it with water and spraying that around will also keep spiders at bay. they taste w/their feet - so they will NOT cross anything that 'tastes' citrusy--or for that matter peppermint.
mice and other rodents do not care for peppermint or for other mint plants. many people will plant mint in pots to keep around the outside of their homes--just to help with keeping them out of the house. It spreads so fast if you plant it in the ground, that people generally will keep it in pots to keep it under control.
I have also heard about bay leaves helping to keep insects away. My mother use to leave a bayleaf in areas for that reason. I believe bay leaves and mint also keep ants away. I do know ants don't like cinnamon or chili pepper or even vinegar. dilute some vinegar in a spray bottle and spray areas to keep them away--though obviously this wouldn't be done in a linen chest. sorry--got carried away here, I guess.
lavender, peppermint, cloves, bay leaves, citrus---those are the best remedies I guess.
