I have heard that mosquitoes do not fly once the temperature drops below 55°F. What temperature does it have to be above for yellowjackets to be out flying? I serviced a few accounts recently while the temps were in the low 60s and didn't see many active flight paths. Now that the temps are back into the 80s-90s, the areas I previously inspected three weeks ago have activity.

I’ve used DeltaDust on yellow jackets this year and had so-so success with it when compared to last year. I shared this with another tech from another company and he said the same thing. Has anything changed?

A new customer has asked me about wasps that dive bomb their pool and make swimming difficult. The wasps are from a large open field next door that has no access. Can anything be done to divert the wasps away from the pool area?

How come hornets are not called hornets? In east Texas, a yellow jacket is a small yellow paper wasp. A hornet lives in large paper nests that can be anywhere. When I try to find pictures, I can’t find them on Univar's website.

During what season are wasps most active? Is it spring, summer or fall?

You once stated that Onslaught could be mixed with baits for yellowjackets. Are there traps for this and how would it work?

It is autumn in New England and holly bushes are being swarmed by wasps, bees and other insects. I believe this is caused by aphid secretions and the holly flowers that bloom at this time. Are there any treatments that will help deter this from happening?

I've been treating a 3-sided shelter that houses horses and the horse owners are complaining about wasps stinging the horses. I've dusted the voids and sprayed around the shelter with Transport Mikron, which seems to help for a few days and then the problem begins again. Any suggestions? Would some type of repellent work better? I know I'm killing the existing wasps, but within a matter of days...

I have a client who has a well head infested with Polistes dominulus wasps. The nest was
exposed when I removed the metal cover and it is sitting on the wiring at the top of the tube. Any pesticides used here would likely drip down into the water supply 20 feet below. Any suggestions on how to treat this and with what product? Dusts and liquid sprays seem
dangerous and I don't want to get ...

I was just curious about the life cycle and habits of Cicada Killer Wasps. I've never seen as many as I've seen this year.
Submitted by Nathan, MA
I have a customer who has a serious cicada killer problem. He has a very thick lawn that he waters to prevent them on his property. The neighbor to his left does not water his lawn and has a much larger number of the wasps and the property to the right has no vegetation and has many wasps as well digging into the sides of the hill. It also has a large drainage pit for the development. I'm out o...

I'm a PMP in Washington and this year wasps are becoming the pest of the year. What product or products do you suggest along with the best eradication methods to nests that are apparently visible?

I live in Central Texas. On our Oak trees are BB-sized balls glued to the leaves - thousands of them per tree. I've been told these balls are from wasps. Could you please give me more data?

I have a client that has an infested tree with around 50,000 wasps in it - it's incredible. Can I spray it with my gas sprayer with Dragnet?

Realizing that maxforce bait or any other ant bait is not registered for the control of flying insects, I wonder about these baits killing yellow jackets or ground hornets that come in contact with it? In the old days "baits" used for hornets, yellow jackets, etc, were compounded with a sweet attractant. I am a PCO from Massachusetts. Thank you for your time and consideration.

I have a homeowner who has red wasps flying around the exterior and sometimes getting inside. The house has vinyl siding, and they seem to be behind the siding but I can't really tell. It has a high roof line which makes it difficult to inspect. Is there anything I can do to maybe draw them to a trap? Any suggestions will be greatly appreciated.

I live in Utah and wasps have been pretty bad this year. In the past years we have been able to keep wasps from nesting on our customers' houses with Demand CS. This year it has not been as effective. Could you recommend a better long-lasting product that would keep wasps from buildng nests on our customers' homes?
