"Bob was intensely honest. At initial inspection he identified the pests in the ceiling as mice (not the chipmunks I thought) and made recommendations as to how we can control them ourselves rather than spending more money on his services. We are very pleased."

"Alan came out to look at the site and do some measurements.  Then we communicated several times by email.  He was very good at keeping me informed of his schedule and the likely date he could complete the project.  He came out when he promised, and finished the work in just over two hours.  I was present as he did the work, and I was amazed at the speed at which he completed the task.  He also sent me an invoice by email the same day.  He offered a lower price upon completion because of how he could save on the wood costs.  I paid him the full price we had agreed upon verbally because I felt he deserved the bonus for his commitment to cost control.

Pest Control FAQs, answered by experts

As with anything ingested by animals, there is always a chance that mushrooms will be toxic. Clearing the tops of mushrooms from the soil to prevent them from being eaten by pets is always a good idea. Since poisonous mushrooms can be deadly, we recommended that any mushroom ingestion is treated as a veterinary emergency. Watch for signs of lethargy and digestive distress in any animal suspected to have eaten a mushroom and contact your vet immediately.

Roaches won’t sting your pets and don’t have venom like spiders do , but they present other dangers. Cockroaches are notorious carriers of diseases like salmonella and parasites like tapeworms. Because they’re so dirty, their bites (otherwise harmless) can also get infected. You don’t want your pets chasing and trying to eat cockroaches, or sleeping near a roach infestation. 

Many brownish housebound arachnids could be mistaken for hobo or wolf spiders, including nursery web spiders. An easy way to classify is to look for traditional spider webs, as neither hobos nor wolves participate in this practice.

Roach spray usually starts working almost immediately on contact—within seconds to a few minutes. However, if it's a residual spray designed to keep killing over time, it can take hours or even days to fully affect roaches that come into contact with treated surfaces. For larger infestations, it may take at least a week to see a noticeable drop in activity, since not all roaches are exposed at once.

For years, it was believed that hobo spider bites were incredibly dangerous, causing flesh-eating wounds. But the rumors of their bites were greatly exaggerated, and there's been no real evidence showing a connection between a hobo spider bite and necrotizing wounds. 

That said, the spiders can and do bite, usually as a defense response. They won't attack you unprovoked, but if you take them by surprise and get close enough, they may bite you. Their bites may cause some minor irritation or itchiness.
