Mosquitoes in McAllen after heavy rain: what to do

Will there be more mosquitoes in McAllen after a big rain?

Very likely. On Nov. 8, 2026, McAllen got 1.84 inches of rain, a daily record for the airport (National Weather Service Brownsville, McAllen climate report, Nov. 9, 2026), and container mosquitoes can go from egg to biting adult in about 7 to 10 days (CDC, Life Cycle of Aedes Mosquitoes). The fastest way to get bitten less is to find and clear the water in your own yard soon after a rain, before those eggs hatch.

How much rain did McAllen get on Nov. 8, 2026?

More in one day than the first nine days of November usually bring. Here’s what the numbers show:

A new daily record. The 1.84 inches at McAllen Miller International Airport on Nov. 8, 2026, beat the old Nov. 8 record of 0.84 inches set in 2016 (NWS Brownsville).
Four times the normal for the month so far. Through Nov. 9, McAllen had 1.90 inches of rain for November, against a normal of 0.44 inches for that stretch (NWS Brownsville).
Street flooding in South McAllen. Early Sunday, the National Weather Service put south-central Hidalgo County, including South McAllen, under a flood advisory for minor flooding (Hoodline, Nov. 8, 2026).
It’s still warm. Sunday’s low at the airport was 66°F, 4 degrees above normal (NWS Brownsville). Warm, wet weather is what mosquitoes need.

McAllen has seen this pattern before. In March 2025, the city got 9.13 inches of rain in three days (Texas A&M Office of the State Climatologist, March 2025 Climate Summary). Big rains here leave water sitting in yards, gutters and low spots for days.

Isn’t mosquito season over in November?

Not in the Valley. Hidalgo County’s vector control team runs mosquito surveillance during arboviral season, which it says typically runs from June through November (Hidalgo County Health & Human Services, Vector Control). In a mild fall, a soaking rain in November can kick off one more round of biting.

Which mosquitoes will be biting in McAllen yards?

The main one around homes is the yellow fever mosquito, Aedes aegypti. It’s small and dark with white markings, and it bites during the day. The CDC says it lives indoors and outdoors, prefers to bite people, and only flies a few blocks in its lifetime (CDC). So the mosquitoes biting you on the patio most likely hatched in your yard or the one next door.

Where will mosquitoes breed in my McAllen yard?

Aedes mosquitoes lay eggs on the inside walls of containers, just above the waterline. The CDC says those eggs can survive drying out for up to 8 months and hatch when rain fills the container again (CDC). That’s why a big rain after a dry spell matters: eggs laid weeks ago can be sitting in your yard, waiting for water.

Walk your yard and check:

Buckets, plant saucers, kids’ toys and pet bowls
Old tires, tarps and grill or boat covers
Clogged gutters and downspouts that drain into low spots
Bird baths and fountains
A/C drip lines and leaky hose bibs that keep the soil wet
Low spots along the house or fence that stay muddy for days

McAllen’s health and code enforcement director gave the same advice after an earlier round of rain: “If there’s toys, tires, buckets, birdbaths, swimming pools, tip those over — drain them out. Mosquitos grow very quickly” (KRGV, July 3, 2025).

Free inspection. Not sure where your mosquitoes are coming from? Chris will walk your yard, point out the breeding and resting spots, and give you a price before any work starts. Book your free inspection or call or text 956-287-2118.

Doesn’t the city take care of mosquitoes?

The city helps, but it can’t treat your backyard. The City of McAllen has a Vector Control Team and a mosquito surveillance program run with Texas A&M, Texas A&M AgriLife, UTRGV and UTEP (City of McAllen, Health & Code Enforcement). In July 2025, after several days of rain, the city sprayed the parade route and said crews would spray the entire city, weather permitting (KRGV, July 3, 2025).

City spraying targets adult mosquitoes in streets and public areas. It can’t reach the eggs in your flowerpots or the shady, damp spots behind your house where adults rest during the day.

Frequently asked questions about mosquitoes in McAllen

How long after the rain will mosquitoes get bad?

Aedes mosquitoes can go from egg to adult in about 7 to 10 days (CDC), so expect more biting in the week or two after a big rain unless the standing water is cleared.

Why am I getting bitten during the day?

Aedes aegypti, the main mosquito around Valley homes, bites during the day. It rests in shady spots near the house, so patios and side yards are where people notice it.

Why doesn’t the city spray my yard?

City spraying focuses on streets and public areas. Mosquitoes breeding on your property need to be handled at your property.

Is the mosquito inspection free?

Yes. The onsite inspection is free, and you’ll get a price before any work starts.

Do you serve the rest of Hidalgo County?

Yes. CPL serves McAllen and nearby cities like Edinburg, Mission and Pharr, plus the rest of the Rio Grande Valley.

I used CPL last year for a termite problem. They did a great job protecting my house and keeping me informed! This year, I saw some termites in my yard. Chris inspected and assessed that they were not getting into the house. He sprayed that area to get rid of them and then sprayed my trees again just as a precaution. All this and he did not charge me for the visit!! Talk about excellent service! I highly recommend CPL and will continue to use them for my pest control needs.

I had a severe case of mole issue in my front yard. Digging everywhere and destroying my lawn . Christopher came and treated the yard with carbon monoxide. The first try didn’t work but he came back 2 times after that with no charge. Now it has been about a month after the last treatment and I see no sign of the mole. Great company . Christopher is awesome. Do not hesitate to call him for any issues you might have. Trust me. Mars

Chris at CPL was professional and knowledgeable and thorough in his pest inspection. Though he certainly has services he could have sold me, apparently my own initial attempt got lucky and appeared to have cleared out my problem, and he was honest about this evaluation. That type of honesty is just the thing that would have me coming back to CPL in the future, should the need arise. Thanks!

Thank you, Christopher, for the exceptional service! We had early signs of a termite infestation and Chris came out and treated the affected areas in one day and they are completely gone. Today I had him come out again for an ant problem outside. Will be a life-long customer. Thank you. :)
