Part of our issue is in the basement. Seems to be more fleas there than anywhere. All of the treatments I read about on here seem to focus on carpet and furniture, it’s not clear what works well on cement (and hardwood really).
The control methods mentioned on our How to get rid of fleas page should all work in a similar fashion on hardwood and cement. However, since fleas develop in dark, protected refuges (such as deep within carpets), on other floor types they are most likely to be found in cracks in the flooring, near baseboards, and in other areas where debris collects. If there is an area rug, this could also be a hot-spot. These locations should get the most focus with vacuuming and chemical treatments.
Pyriproxyfen (Nylar) is an insect growth regulator (IGR) and is commonly used to combat fleas. It has been shown to be effective on concrete and wood, as well as other materials. Here’s that related study. So if you have a choice of products, look for the IGR pyriproxyfen (Nylar) instead of methoprene (Precor).
Martin’s IGR is a good choice for a pyriproxyfen concentrate. The size it comes in is good for indoor use.
I apologize for the delayed response time. Warm regards,
