I don't know but we have cats and to be safe keep them away from the area that has just been sprayed for a day or two.

Chaindrite liquid has to be diluted around 14 to 1 and is soon absorbed into the ground. there is a leaflet inside the box that will tell you all about it. 

I  do not trust the chemicals that pest control companies use with animals, if anything they are over strong,  they use too much and are sometimes not so careful where or how they spray, better do it yourself every three or four weeks is enough.   

Got it, Thank you.

And thanks Banglay for the instructions.
