(To start off, I want to mention that I live in Phoenix, AZ and I have a Bermuda lawn with full sun.)
I have recently assumed control of the lawn! Apparently since we are renting our house, my dad doesn't care about the lawn so I have made it my mission to turn our lawn green. The grass isn't that bad, but has a couple of sparse/bald patches. I bought some EZ Seed stuff that was supposed to fill in the blanks and tested it on a small area to ensure that birds wouldn't bother with it (like the label said). After a couple days I was satisfied that birds would leave it alone and spread the seed heavily on the bald patches and lightly over the rest of the lawn. As I was pulling weed I realized that ants were crawling away with my seeds! I don't want to really get rid of the ants because I know they help to aerate the lawn (and mine can use it) so I don't want to kill them, but I want to prevent them from taking the seeds. I was thinking that I would drop the seeds and sprinkle cayenne pepper on top. However, I want the ants to have free reign over the lawn AFTER the bald patches fill in. Will the pepper eventually fade? Or will they avoid those areas for an extended period of time (like a year)? Does my plan have a good chance of working?
I find it funny that I am becoming intimately familiar with what is going on on the property. It seems that those thieving bastards took my seed investment and have used it to expand the colony. I was checking our drip system and I found a new ant mound forming and spent a few minutes marveling at the ants removing dirt from underground...
