Spider sprays – limitations and legalities

The most important limitation: All spider services are spider reduction services. There is nothing we can spray that is so toxic that once it dries it will kill every spider that crosses over it. There never has been. But there used to be more effective materials. What happened? The general public demanded safer and safer pest control products and safer application procedures. We use the very best spider control materials currently available, in the quantities and ways that we are allowed to by law.

We have excellent reviews on Yelp, Angie’s List, and other sites. Our truck are all GPS enabled, so we know how long our techs are on site. We stress customer service above all else and we have an active quality assurance program. If the level of spiders you continue to experience after a service is too high, we can perform additional services, but we will need to charge for them. We didn’t change the laws, and we didn’t remove highly effective pesticides with proven records of safety from the market.


Exterior limitations

Exterior sprays kill 85% (possibly more) of  the spiders present at the time of application. If you live next to the water, or are surrounded by vegetation – you will see more returning spiders, sooner. Some homes, especially in these areas, may wish to have a second treatment within thirty days – especially in the fall, some years are worse than others. If your siding is dark, we will use a different formulation than if your home is lighter, it will not last quite as long, and is not quite as effective. The regular formulation leaves a faint light colored residue which is not typically noticeable on light colored homes.

We cannot spray any vegetation in bloom, or in such a way that sprays could drift onto plants in bloom. We make every effort to not spray any plant that is meant for or could be meant for human consumption. We cannot treat plants that occur ten or more feet away from your home. If you plant fruit trees against your home, or a garden – that area is not going to get sprayed. These are state and federal regulations. If you want vegetation sprayed within ten feet of your home, it must be very hardy, inedible, and you must sign a hold-harmless. All pesticide sprays have at least a limited capacity to damage plants. To spray plants, we must highly dilute the spray and that does make it less effective.

There will almost always be some over-spray on windows.

We cannot spray toys, dog chews, bird feeders, or bird baths – if there are a small number of these items, we will move them. If there are a large number, we will not spray those areas.

Pets cannot be in the spray area, and neither can you, unless you are wearing the same Personal Protective Equipment that we are required to by law and you are trained as an applicator.


Interior limitations and legalities.

Whenever we spray the inside of a home, people must vacate. If we spray any part of the home except the garage, all people must vacate from all areas. Care must be taken to protect birds and aquariums – call us. We prefer that pets are out, but if they cannot be out, they must be put in areas that we will not treat.

We prefer not to treat the interior of any home with spray insecticides where someone is experiencing a health sensitive situation. We would rather use baits, glue traps, vacuums, steam, etc…


If you just suffered a stroke, you could experience complications, because of the stroke – not because of us. If you are undergoing chemotherapy, your life is already pretty complicated. Children are naturally most likely to experience complications within their first six months, and people who are pregnant are typically going to have any problems, if they do, within the first two trimesters.  All of these complications have nothing to do with us, and we honestly hope you never have any health complications, but all of these situations bring an extra level of liability. So we ask you to work with us to find ways to achieve acceptable control levels without spraying until you are at your healthiest and the chances of complications have diminished. Most pests can be handled in some fashion with alternatives to interior sprays.


The National Pest Management Association, and many state pest control associations have adopted good practice statements regarding inside applications. Those good practice statements include phrasing that after initial services have been made to control a pest, interior applications should be limited to once a year.

Instead, the industry is evolving to include Integrated Pest Management techniques, including the use of glue traps to monitor and reduce populations, crack and crevice treatments for kitchens and bathrooms, and areas under baseboards. The sealing off of areas around heat ducts, furnaces, and other areas, to slow down pest activity while decreasing the need for pesticides applied in our living areas.


When we do spray inside:

We are careful not to spray above kitchen counter or tables, unless you have agreed to clean them afterward, and they are free of dishes or food. We don’t spray pantries – unless they are empty. We don’t spray above toothbrushes or anything else that might go in your mouth, the mouths of your children, or your pets – including toys. We avoid spraying where the material could drift onto computer screens, big screen TVs, highly lacquered wood finishes, hard shiny plastics, or paintings. If your pet is home and out – no spray. If we see an uncovered aquarium, we will not treat that room. If we notice a bird in your home, we wont spray at all, if we notice it first.


What doesn’t effect our treatments?


If you have eaves, like most homes in the northwest, then 90%+ of the area we would normally apply is dry – even when it’s raining, unless we are experiencing driving rain – at the exact moment we are applying. Driving rains are unusual in our area. We normally have drizzle or on and off sprinkles. Our chemicals dry fast, typically within a few minutes and rain drizzle or light on again / off again rain will not remove it, certainly not from sheltered areas.

If you do not have good eaves, if your home is dark colored ( we use different materials for dark homes) or if the rain is heavy – we will automatically reschedule your home to a time in the day when it is not pouring down, or to another day.

It is important to know that materials we commonly use for spider control, are not rain soluble and stay right where we spray them. These materials are designed to out perform rainy weather – that’s one of the reasons we use them.

What does break down the pesticides and make them less effective? Sunlight. Heavy sun doesn’t just fade your carpets, it breaks down pesticides.
