I have called the exterminator twice within the span of about 2 weeks to treat fleas indoors. I was wondering if it doesn't last long, or does it just kill the fleas that are on the ground at the time...My dog is on a topical monthly flea treatment, but she seems to get bitten as soon as she comes back into our home despite having the place sprayed twice with the product...Any answers will be helpful. Thank you
Dragnet SFR does have a residual but it is not typically very long. Only a few weeks. However, the bigger issue is if the company did not use an IGR, which is an insect growth regulator. IGR's are essential when treating fleas because it prevents them from reproducing and laying more eggs. Also, Dragnet SFR will not kill flea eggs, so when the company comes to spray they are probably killing some of the adults but not any eggs. So after they leave and over the next few weeks you have new flea eggs hatching. This is why our indoor flea kit comes with an easy to use aerosol can with flea killer and IGR in one can. Also, you should be vacuuming thoroughly before the flea treatment and then you need to treat exactly 14 days later since flea eggs hatch every 2 weeks.
