Good morning. We have a local bug company come and spray on a summer program for 6 months. It's done as a preventative measure. Any ideas what the name of the insecticide these guys use? It must be some sort of general purpose insecticide. It's sprayed around the foundation of the house, as well as inside. It must be safe for animals too because of the cats, etc. I've never had the chance to ask the guy who comes. Thanks.
Do they have a telephone number?

Probably Cypermethrin, a synthetic insecticide concentrate that is non-toxic to humans or animals when dry. Sold under the label 'Demon WP', for one.
Only a total idiot would allow anything to be sprayed in or near the home without knowing what it was. Congratulations. You are a total idiot. Please kill your kids before they can vote, reproduce, or drive cars.
Seems like all you see either professional or do-it-yourself any more is pyrethroids. (Why is that?)
They are required to leave an invoice with the name of the product used, how much was used and at what percent. Sure it was one of the pyrethroids, there are a few that are commonly used as you describe.

Well make that low toxic to humans, it is probably used 35 times or so less than T salt at label dosage, but it does kill insects so can be toxic. Cypermethrin is what I mainly use myself in my business but actually most companies seem to use the newer generation of pyrethroids such as bifenthrin, Cyfluthrin and Lambda cyhalothrin.

Well the main reason is the older common insecticides such as dursban and diazinon are off the consumer market, for a number of years now and can no longer be applied by pros in areas where kids may be found. The reason most pros for years have used pyrethroids are that pyrethroids act faster than the older organophosphates (dursban, diazinon), insects are more sensitive to them so the usage rate is a lot less than the OP's (dursban would be used at a rate from .5% to 1%, I use cypermethrin at rates from .025% to .1%). And some of the pyrethroids effectiveness lasts longer than the OPs so instead of monthly services we area able to service every 90 days.

Glad I "stocked up" back then
The pyrethroids definitely are a better product and most don't have the hard chemical smell of those two.
