Answer by Chewy • Jan 14, 2020
Keep children and pets off and out of treated area until the product has completely dried. After dry, the area is completely safe for your children and/or pets. This treatment may be applied to grass, however it does kill certain types of grass including bentgrass, Bermudagrass, bluegrass, fescue, Irish moss, merion and St. Augustine lawns.

This may not have worked

I sprayed my yard and screened in patio 3 days ago and I am still getting fleas off of cats. I believe I combed them all off the night after I sprayed. Two days later and it seemed like they had more fleas on them. I sprayed a second time with a different chemical. Anyone else had any failures?
