We bought Termidor last summer after an exterminator couldn't wipe out our any problem after 3 visits in one month. It worked great and we've used it again twice since, once in fall and once a week ago (May). No ants, yay. BUT... We have a good amount of silverfish still and the worst of the worst: centipedes! Lots of them. Today alone I found 3, and not just in the basement. So anyway, this Demon product gets good reviews for centipedes. And it doesn't sound as scary to use as the Termidor -- I like that we can use it inside as well as out-- but can I overlap the two? Demon inside and out, so soon after Termidor outside?
We would not recommend using the Demon WP after the Termidor SC nor would you want to. Termidor SC is a non-repellent product that works with a delayed reaction time and a transfer effect to help kill off colonies of social insects such as ants. Termidor SC also has a very limited label that only allows you to use it on or immediately adjacent to a structure. Demon WP on the other hand is a broadly labeled synthetic pyrethroid that will kill the insects that walk over treated surfaces. If you use the two together you will be losing the non-repellent factor and transfer effect of the Termidor SC. Termidor is labeled for centipedes and silverfish it will just take longer to kill them. You could use the Demon WP on the inside and the Termidor outside though and many customers choose to do just that.
