Q
what works better on German cockroach, tempo wp or demon wp?
A
Tempo Ultra WP and Demon WP are both labeled for various types of roaches. They have two different active ingredients in them, which is the main difference. We would not recommend using just one product to control roaches. A bait gel and IGR (insect growth regulator) should be added to ensure that you are maintaining control of the roaches.

Q
Is Demon WP labeled for Bed Bugs
A
Demon WP is not labeled to kill bed bugs. If you are looking for a liquid concentrate that is labeled to kill bed bugs, Temprid SC is a great product that we recommended for bed bugs. We offer Temprid SC in our complete Bed Bug Kits that come with a number of products recommended to perform a full bed bug treatment.

06/25/2015maayan from las vegas asked:

Q
Can Demon WP be mixed with Suspend SC?
A
Demon WP and Suspend SC should NOT be mixed together. There is no valid reason to mix Demon WP and Suspend SC together.  Suspend SC is a synthetic pyrethroid and Demon WP already contains a synthetic pyrethroid, so there would be nothing to gain by mixing these products together. Making a pesticide too strong can actually backfire. Areas that are treated with this overly concentrated spray will be repellent and insects will simply avoid the treated areas prolonging the infestation.

Q
Is it normal to still see fleas after the first Demon WP Insecticide treatment?
we just moved into a house where te previous owner had a dog. We don't have any animals but are getting tore up by fleas. We sprayed 1 treatment and are still getting bit. Not as bad but still.
A
 Demon WP Insecticide  will not eradicate fleas. You will also want to  mix in an IGR like Precor IGR to break down reproductive cycle. It can take multiple treatments wo eradicate fleas.

Q
Question about spray bottle.
Hi, I do not have access to the kind of pump sprayer recommended and I will not be able to obtain one, so I need to improvise. It says to mix Demon WP up in a gallon of water. Can I then put it into a standard spray bottle and apply it this way? I really don't see what the difference is in how it is applied. Please do not just tell me to buy a sprayer because I cannot afford one. What am I asking is, if I apply it this way, will it still work? Thank you.
A
The only way you could apply the Demon WP in a spray bottle would be if you diluted it in a gallon water first and then poured into spray bottle.

Q
What product would be good to use for brown recluse spiders?
Bought a house last fall which turns out to have confirmed brown recluse. I have some Demon WP left but need to re-order. Should I stick with Demon for inside and outside control or switch to Onslaught Scorpion & Spider? I'm also planning on ordering/using Talstar PL granules outside. Thank you!
A
Demon WP is labeled for spiders, however with using the same product for a long period of time insects can become resistent to that active ingredient. You can solve that problem by simple switchning to another product with a different active ingredient such as Onslaught FastCap Spider and Scorpion Insecticide which is also labeled for spiders.
