Destroy the eggs, reduce the risk of diseases like dengue fever and malaria. 

That's the theory behind Laurentian University professor Dr. Gerardo Ulibarri's "ovitrap" experiment, which is now headed to Guatemala.

Ovitraps work on eliminating future generations of disease-carrying mosquitoes by attracting and tricking them into depositing eggs onto a rinseable strip in a bucket.

As mosquito eggs are destroyed, the risk of future infection among humans goes down. 

Ulibarri has already tested the device in Sudbury to catch West Nile-infected mosquitoes, and in Mexico to catch dengue fever-infected mosquitoes. 

In the latter case, Ulibarri says that just 50 of his modified ovitraps reduced mosquito eggs by 70–80 per cent in a certain area compared to unmodified traps.

And the simple bucket and pump system has attracted more than just flies: Ulibarri has received a $112,000 federal grant to deploy his traps in Guatemala.  

Ulibarri spoke with CBC Sudbury Morning North radio show host Markus Schwabe on Wednesday.
