Bromeliads and mosquitoes

If you have bromeliads, you have mosquitoes breeding in the cups. Unless, of course, you manage them well. I'm using mosquito bits containing modified Bt, available online, to kill the larvae.

I asked Adrian Hunsberger, the horticulturalist/entomologist with Dade's extension service, whether it only need be applied to the central cup, but she said bits should go in each cup and reapplied if it rains.

According to, the larvae live in water for seven to 14 days, depending on the temperature, so I reckon that applying the bits need only be done once a week.

Despite that, I have a major skeeter problem, and I suspect that they are coming from the neighbors. I've called 311 to request spraying, but so far, I've not noticed any less. I should buy shares in Johnson & Johnson, the manufacturer of Off.

It never would have occurred to me that people who grow Broms would have mosquito problems. Thanks for the tip. I'm going to pass this on.
