User questions & answers

Question:	how long does these last? worked in garage but not inside house any suggestions
Answer:	It doesn’t even list roaches on the box. When I received it the box didn’t represent that it helped roaches AT ALL. They’ve emailed me multiple times asking me to take down my review where I pointed this out with a refund in return. I have not done so because the item is falsely advertised.
Question:	Can i put this in the roof is there a version for that
Answer:	All I can tell You is that since installation I have not seen a single Arachnid or Insect.
Question:	What are the main different points of pest repellent sprays and ultrasonic pest repellent
Answer:	I don't know about ants (I do not have that particular problem). I bought them for Mosquitos, Flies and other flying objects (I live very close to a River.) Took about 3 weeks then seemed to work PERFECT. Hope this helps.
Question:	Do these harm cats
Answer:	No, I have a cute cat in my house. It seems that my cat cannot hear the frequency from the device. It has no effect on my cat at all.

Answer:	My hunting unit did that. Checked everything and believe the red flame was just impurities being burned off on the first cycle.
Question:	Is the light always on
Answer:	The active ingredient in this product is allethrin.
Question:	Does this work outside
Answer:	Probably not advisable to use around CATS! See Wikipedia excerpt about Allethrins below: “The compounds have low toxicity for humans and birds. It is highly toxic to fish and aquatic invertebrates. At normal application rates, allethrin is slightly toxic to bees.[1] Insects subject to exposure become paralyzed (nervous system effect) before dying. Allethrins are toxic to cats[2] because they either do not produce, or produce less of certain isoforms of glucuronosyltransferase, which serve in hepatic detoxifying metabolism pathways.[3]”

Question:	Does this work on lizards
