Is your yard the mosquito habitat and with all the debate going on about Zika virus, maybe we need to figure out where they are breeding? I have seen beer bottles with an inch of water holding up to 25 wiggler mosquitoes, so anything with standing water tends to be the culprit. Check your property first, then start to spy other areas that me well be the cause. There are different species and they do different things. One mosquito will travel 1 mile for food, while another likes to stay close and feed. What time do they tend to bite, all these little things helps the Pest Management Professional to decide on the treatment protocol. Did you know that adult mosquitoes make up part of the diet of some insect-eating animals, such as birds, bats, adult dragonflies and spiders.
So first off walk around the house see if there is anything holding water – pour it out.
Check old tires, they are notorious for holding water.
Check drip or flood irrigation. I know we live in AZ but some areas are constantly wet, so check low lying areas.
Think about tree notches.
How about water meter boxes?
Don’t just look down, check gutters as well.
