magic no-flea and no-pestilence spell

 The spell I found useful is the no-flea and no-pestilence spells. They can be formed anyway that you want, but here is the form I like.

 The magic no-flea no-pestilence spell works 80% of the time, but causes no fleas or pestilence in an area. Thought on, while doing the spell. The spell be to state, 'nay-fle' [pronounced nay-y fleh] for the anti-flea spell.. and 'nay-mey' [pronounced nay-y me-why] for no pestilence.
