Bugs and Smells
This seemed like an easy way to protect from mice. I did try this out for a few months and was not impressed. What ended all mice attacks was hard work. Everything was first put in a plastic bag, then shut in a box. I also was very careful about picking up/sweeping out all crumbs. Once I found the Cab Rodent Repellant I was very happy with the smell and the effect. In extreme circumstances I spray the tires with ammonia.
Keep the inside of the truck smelling fresh : grow lemons.
Use organic lemon seeds because some non-organic lemon seeds may not germinate.
1. Soak the lemon seeds for 24 hours.
2. Gently pat dry.
3. Carefully peel the outer shell – do not damage the inner seed.
4. Plant the seeds approximately one-half inch deep in the potting soil, moisten the soil slightly.
5. Add just enough small pebbles to cover soil. Cover the top of the pot with plastic wrap so that the seed soil will not dry out.
6. When you see the lemon seeds sprouting remove plastic wrap. Be careful not to over water – soggy seeds will be a fungus.
Your lemon tree will very likely produce tasty lemons in about 15 years.
I never tried this. The temperature swings were too great in the unheated/cooled truck bed. But the idea sounds so great.
