Category:Not effective

Any treatment, product, chemical or other item marked with the 'Not effective' category has been tested and proven not to work to kill, repel, destroy or control invisible biting mites.

This does not mean that it won't work against other insects or in other situations. These items are flagged here as members of this wiki have tested them and proven them not to be effective.

Try it for yourself. Unless it is marked as being dangerous or Not Advised; and in which case try something else first.
