Outdoor flea infestation

Asked July 29, 2019, 8:09 PM EDT

We have an flea infestation in one part of our yard only. They are also concentrated on the concrete near our front door. The exterminator has come out and sprayed twice. We have applied DE, flea spray, insecticide granules, etc. Within 24hrs, they always return. We do not have pets but there are some neighborhood cats that roam around. What can we do and why do they seem to proliferate around the concrete??

Thank you for your question. I suspect the insect has been misidentified, but that your own county Extension office can rectify that and provide correct control recommendations. Here is their webpage to contact them: https://extension.tennessee.edu/hamilton/Pages/default.aspx Good luck!
