This is what a friend uses in his garden that helps repel pests and bugs. It seems to work as I no longer have a rat infestation around my house!
You do not need a lot of this stuff to work.
This is what I use. If it rains, reapplication required; not toxic.
1 C alcohol
3 TBS hot sauce (no seeds for sprayer)
3 tsp liquid dish detergent
1 gal water
1/8 C alcohol
1/2 TBS hot sauce (no seeds for sprayer)
1/2 tsp liquid dish detergent
Remember, NO SEEDS, they will clog up the sprayer. I use an old windex or febreze sprayer and run the mixture thru a sieve (NO PULP EITHER).
