It may be that there are other animals under the deck. I am hoping to trap them asap
Tekko Pro Insect Growth Regulator will need to be tank mixed with an insecticide labeled to kill fleas such as Talstar P as an IGR used alone does not have any killing characteristics to it, it only works to help stop the growth cycle. This tank mix solution can be used to treat the exterior perimeter foundation, landscape beds, lawn areas, etc. For treating hard to reach areas such as under decks, you could consider using an ULV Fogger with an approved ULV Fogging Concentrate such as Sector Misting Concentrate for a contact kill application. Fogging Concentrates do not leave any residual behind but can be used for an immediate kill and followed up with with the Tekko Pro and Talstar P mixed solution for the 21-30 day residual. Fogging applications can be reapplied at 7-14 days if needed. Catching and trapping any wild animals in the area and under the deck is recommended to help eliminate fleas.
