🦟🤫 Ms. Mosquito’s Secret of the Week!

Psst… got animal troughs? 🐴💦
Ms. Mosquito says, don’t let them become her nursery!

Mosquitoes love standing water, and troughs can be the perfect place to lay eggs. Keep that water fresh by dumping and refilling regularly to help send those pesky mosquitoes packing! 🦟

Ms. Mosquito is back!

Did you know that a single female mosquito can lay up to 300 eggs in one egg raft?

These eggs then hatch into juvenile mosquito larvae within a few days and develop into adult mosquitoes after one week!

Mosquito "Buckets of Doom" sound like a clever DIY solution, but they're not the great idea they're made out to be.

If they're not built or maintained exactly right, they can become mosquito breeding sites instead of mosquito traps. The active biological larvicide (Bti) loses potency after about 30 days and requires regular reapplication and upkeep.

The biggest issue is that they can give people a false sense of security. One bucket won't solve a mosquito problem if there's standing water elsewhere around the yard. The treatment targets only aquatic larvae and does not kill adult mosquitoes already flying around and biting humans in your yard. Regularly emptying containers, cleaning gutters, changing birdbath water, and eliminating breeding sites are still the most effective ways to reduce mosquito populations.

Before jumping on the latest DIY trend, it's worth asking whether it's actually improving the situation or just creating another container of standing water. Sometimes the simplest mosquito control methods are still the best. Remember to always DUMP & DRAIN after the rain
